I d say you are lucky it does have pressed forks,tubular forks would have been sold on ebay ,and long gone....It seems a pretty simple resto to me,there are a lot of hard to find bits there......If you cant find a JAP at a sane price,they probably also used the little cheapie 250 Rudge motors that seem plentiful.

Up to about 30 years ago guys used to bring trailer loads of belt drive frames to swapmeets.Never any forks or engines tho.

Albion boxes were also used in things like small tractors and motor my collection I also have an exact copy of a 3E,but without any Albion marks,and the gears are marked "Diecut" ,a name that also appears on replacement sprockets,so I assume its a locally made knock off....Lots of Albion boxes have space for a reverse gear,and in bikes this space could also be used for a four speed.

There is no such thing as unfixable...........years ago,when I had a crane truck,I picked up a 1904 Moon chassis,with a crankcase with four rods and pistons stuck up in the air.......might have been a steering assy and a ally diff housing  too,dont remember......I said.....Youll never get that going......two years later ,it was a going ,driveable chassis,and wooden bodyframe started nothing is unfixable.......yet the original owners of these little poppers couldnt do the simplest maintenance job on them.

You can already see the effect on some other things that were collectable,and changing hands for large sums a few years ago.....old tractors being a good example.....lot of them are now being sold for scrap......Steam stuff reached astronomical heights a few years ago too,but it sort of marks the owner as a millionaire......but prices are coming off from very high levels......Bikes have also suffered from safety aspects.....mainly due to the young car driver not paying attention to driving,while giving 100% to the next text/call/facebook/etc.

Up to around five years ago,everyone had a story of a 1970s jappa with a years use kept in a bedroom or study....and they got it given to them.Now jappas are worth serious money,and no one is giving them away......Cept my nephew gave me the DT175 he bought new......what a wreck.....he sure knows how to destroy vehicles......his new Yammy is driven straight into the back of his new pickup,no ramps,just crash bash.......everything comes easy to the young now,no thought of fixing anything.....just buy new.

I swapped two Kawa 400 twins for a drum of hydraulic oil.......both only around 5000 miles,one kept inside and polished as an ornament.....the other kept downstairs in the shed where children had been playing with it.......the little dears had filled the tank with "petrol"......from a garden hose.....and water had gradually flooded the whole motor.....that was a mess....And the guy had the hide to complain that the oil was used oil.....Although I was impressed by some of the mechanicals.....the alternator was a stationary field coil/brushless type,generally used only on big truck alternators that cost thousands.      And the motor was quite well made.......No ,I still hate jappas.

One thing in general about Sturmey boxes with a quick worm thread clutch throwout is never have the pushrod so short that the end of the quick thread worm can contact the least you will mushroom the mainshaft and thread,and at most the box will burst apart...This throwout carries on thru all the Sturmey descendants to the Laydown box of  1956.......This box seems to have been taken from a restored machine,so its likely in good operating condition.

A rebore will leave the ports sharp edged,so dont forget to bevel the edges .

The biggest catch is ball bearings in odd sizes,which cant be replaced ,unless you make them......The more common LS type have a double ball bearing incorporated with the sleeve gear,and the price of a new made one will lift your hair off.

The inner race is 17mm wide ,but the outer race is only 14mm,and that is the space in the housing.The thin web inside the housing has already been broken away in parts,but with a taper roller that doesnt matter......Incidentally,the bearing should be a angular contact,not a plain ball.So far I havent got to the sprocket bearing,the nut is very tight,and is going to need a rattle gun.Assuming its right hand.I have the army Chief manual,and its not a great doesnt mention that both clutch side threads are left hand,excepting the inside nut on the clutch body.

I have a 1926 Indian Scout gearbox apart,and the bearing behind the clutch drum is a tapered roller,and has had the outer race ground back to suit the space available.The bearing should be a angular contact ball,but must have a narrowed outer race.Dimensions are standard 35x72x17 for the inner race,but the outer needs to be 14 mm wide to fit in the housing.Maybe Ill just leave the taper roller in place,its been there for who knows how long......Where is the best place to get the correct bearing?

out here we got some "Aerostart" type stuff in a spraycan called "Start-Ya -!"%^%".....none of the ether based sprays ever fail to fire up ,in my experience,I would never be without a can or two.

One stroker that wouldnt start,turned out cylinder base gasket had no transfer port cutouts.....Anyhoo,if it wouldnt go,I would hook up a large electric drill to the sprocket,and motor it over at a rate of knots.....This is how I start my rideon lawnmower,since the recoil broke.

I never use any EP oil in a bike,as it turns acid and actively corrosive with water added.Seen too many wrecked gearboxes from EP oil and left unused for long periods,even over winter is long enough for considerable condensation to build up......IMHO,using a good grade of engine oil in the gearbox ,would not cause any problems with normal use.
