Information search : Wolf WA10 "Unit"

[Meelis]

Greetings !

I´m from Estonia and searching all the information there is to find about this certain motorbike.
 A week ago my friend (both of us are members of local vintage motorcycle restorers club : www.tsiklitall.org) told me that he had remains of some small-engined english motorcycle named Wolf (it has "Wolf" transfers on fuel tank).
When we took it out of the garage and compared with the findings in the internet there was no doubt that we have here remains of 122cc Villiers-engined Wolf WA10 "Unit".
Picture from 1937 catalogue :
http://www.localhistory.scit.wlv.ac.uk/Museum/Transport/Motorcycles/WolfUnit1937.jpg
All the parts that are left look exactly the same.
In comparison : there is 1940-version in sales which has already lots of different details (lights, exhaust ports & mufflers etc.). So we think that our version is 1937 or 1938.
There is following info on the frame-badge
Engine No.: 4360
Gearbox No.: 4360
Frame No.: 14281

According to our pre-war archive data there were no local sales-offices in Estonia for these Wolverhampton motorbikes and in the 1940-register there was only one (!!!) Wolf motorbike in Estonia !While in the previous - 1935 dated register - there are no signs of such motorcycle. So it had to be newer than 1935 and presumably it is the same and only that we have in our hands.

Our "remains-of-a-bike" is missing lots of parts though : complete wheels, engine (AA/VIIID), both exhaust pipes and one muffler, front light lens and taillight cover, fuel tank filler cap, toolbox, levers-grips-cables and probably few other smaller parts. That`s quite a lot...
But on the other hand everything else is in one piece and after some cleaning it turned out to be quite well preserved ...+ we already found suitable engine.
 It was found in the attick of some old house here in Tartu (my hometown) and we think it was hidden there in times of WWII. Therefore we are planning to restore this motorbike into best possible original condition and display it in our club museum.

Appart fron above mentioned 1940-version I haven`t found any photos of other surviving 1937-38 models.
Supposedly there was one of these in Belfast (post 27.09.2006 in this thread : http://www.cybermotorcycle.com/euro/brands/wolf.htm). I tried to contact this person via this e-mail address but it is probably not in use anymore.
Another hint about surviving WA10 eas in this thread : http://www.vintagebike.co.uk/forum/index.php?topic=1820.0
It would really be a big help in restoration process if I only could find and contact owner(s) of similar motorbike(s). For example I don`t even know the correct measures of tyres & rims !
I have allready posted information request to VMCC Library but it will probably take time.
We need to order this brochure : http://www.motorrad-oldtimer-photo-archiv.de/shop1/product_info.php?info=p1693_Wolf-Motorrad-Prospekt--6-Seiten--1937------wol-op37.html&language=en

 Can somebody help me with information or photos ?

The joy of restoring a Wolf lies in them being made entirely of common proprietary parts that were sold to dozens of other small firms. In short all of the parts you are missing are common to many other makes. The only part that is uniquely Wolf is the actual frame.
For example, the Villiers power unit comprised not only the engine and gearbox but the lights as well so your missing headlight lens and tailight parts are common to many Villiers powered bikes.
The British Hub Co were the major suppliers of wheels and hubs to the lightweight market and the chances are very high they supplied Wolf as well. I would expect one of the British Hub Co range to just drop right in place. As for tyre sizes, I can't think of any British lightweight of that period that didn't have 19" wheels and run a 2.75, 3.00 or 3.25 x 19" tyre. Usually 2.75 as they were the cheapest.
You are very lucky in that you could identify what you found. Usually the tank decals are gone and it is near impossible to identify an individual make as the whole range of British bikes using the 122cc Villiers engine are so similar.
Firms like Wolf never supplied a great deal of information about their bikes. They didn't need to. Villiers supplied all the engine and lighting information. All that was left was the front forks and wheels which were basically overgrown bicycle stuff so if an owner had owned a bicycle he knew what to do with his motorcycle.
Nothing is that simple today is it. It takes conscious effort to go backwards to a time when the owner did all his own maintenance. Best of luck,

Thank you for your quick response !
I knew that these type pf bikes were made of common catalogue-parts. Wolf (Wearwell Cycles Co.) made only the frame (and maybe mudguards + lots of smaller parts) themselves. Even the fork is very common and I`ve seen it on many other small motorbikes from the same era.
Also I know about Villiers engine and lighting system (the "H-OFF-LOW" light switch could be common Lucas though) and got hints about "British Hub Company"`s hubs & brakes (maybe even complete wheels ?).
It is really hard to judge possible tyre size by this sole catalogue picture ("british" 2,75x19" seemed to be the only reasonable option but as one of my friends has 1936 BSA B2 with 3,00x20" tyres I feared it could also be possibly 20". Though finding out the correct tyre size is not a big problem : it is mentioned in 1937 Wolf Motorcycles sales Brochure (which is in VMCC Library or can be ordered through website mentioned in my previous post). I just thought that maybe someone knows the right size.
Yes it was good that original transfers were readable but there is also this beautiful-shaped "framebadge" where "Wolf" and "Wolverhampton" are mentioned.
The main reason for searching photos, information and owners contacts of the same production era "Wolf Unit"`s is to have a better or even precise knowledge of all the smaller details. In some older post (2006 or 2007) about the same motorcycle you even mentioned one "WA10" that was found then ? Have you got any idea where is this "Unit" now ?
P.S.: has anybody got any idea of such "windguard" that can be seen on this Wolf catalogue photo. Our "wreck" doesn`t have this item. Is it possible it was offered as an "extra" ? It surely adds some british taste to this little bike and we would like to make a replica of it. It is not hard to determin the overall shape from the photo but details are more complicated : was the edge "rolled" into certain profile ? Is the "fixation" bolted to the windguard or did they use massive rivets ? And so on...
Can anybody help me ?
