I don't know about the correlation between frame numbers (if there are any!) and years of manufacture - you will have to google this. The best way to tell the year would have been the engine as they used several (mostly small industrial units) over the almost three decades this thing was built but the engine is obviousely gone.
What's it worth? No idea, but I wouldn't expect too much from it! Best way to find out is to put it on the market somewhow (ebay?). This way you don't have to find out more about it as the potential buyers/bidders will know more anyway.
But maybe it carries an emotional value for you being your late grandfathers ex-mount? That's to decide for you alone! In this case keep it, get information, find an engine, put it all back together (it seems quite complete apart from the missing engine) and have (if not too much, I'm afraid....) fun with it!

yeah i  thin this is a Pannonia but im not sure wich year ....is there anywhere there i can put its chassis number to indentify the year?

is it so important to know the exact year of your machine?

from the look of the engine side covers, the finning of the cylinder and the form of the fuel tank I'd say it once started life as a model TLT from 1956/57....
BUT: the front forks are heavily modified and/or from a later model; the front wheel is from a later T5; the rear wheel, the front and rear mudguards, the solo seat, the twin rear shock absorbers, the tail light and the silencers are certainely not Pannonia; and the side boxes and chain case are missing altogether.

add to this the fact that you obviously do not have matching papers for it - is the year still so important?

if you still want to know: give engine and chassis numbers and I will see what I can tell from that!

P.S.: Where in the world are you?

it's a Panhead. A Knucklehead would have a springer front end.

If you look more closely, your chassis number should read XC8873B25 not XC8873025.
This would be correct within the new numbering system introduced for the model year 1969 where XC means December 1968 and B25 is the model designation. In between is the serial number 8873 which runs on regardless of the model.
Location of the chassis number is as stated by John.

I think you would be very lucky indeed to find a suitable "adapter kit" that really fits your setup without needing any modifying.
What you basically need are a front axle that fits your forks and a spacer of the right dimensions to position your wheel centrally in the forks - not that hard to do if you have access to a lathe.
Show pictures of the parts you have with the relevant dimensions and it will be much easier to determine what needs to be done

Those Deluxe front forks/ action don't look anything like the forks on Keiths dads' bike ?

 No sign of pedals either ?

What's your suggestion then as to the make of the bike, a Harley? 

But you are right, the front forks lack the leaf spring and linkage and the front fender looks heavily modified. The front axle now rests directly in the slots for the spring links - the front wheel is about two inches too far forward now, just the length of the missing links!
But I can still see the second chain on the right side of the bike so the countershaft for the pedal crank is still there. If the pedal isn't just obscured by the rider's leg but really is missing completely he would have to push start the bike as there is no gearbox and kick starter. And where would he put his feet while riding?
The production of the Spacke engine for motorcycle use ended in 1919 at the latest, so if this photograph really was taken in the mid-thirties the bike would have been 15 to 20 years old and could have stood abandoned and partly dismantled in a barn for the last ten.
Maybe the young man found it, cleaned it, put it back together as best he could and just took it out for fun and the picture. If you look closely there seems to be no twistgrip on the handlebar as well!?

Anyway this is a great period pic. Thanks for sharing, Keith!

I'm not surprised that Peter Williams was involved in this. He was/is an excellent engineer as well as a very talented rider.
