If they are damper rod forks then the leak could be from the socket cap bolt which goes through the bottom lug to fix the damper rod. Sealed by a copper washer.

Have you tried phoning the well established UK dealers, who may not list their whole stock on a website. Burton Bike Bits, C and D Autos for example. BBB have an old PDF list on their site, a few years old, but was then listing 66 5541.

Dont know if this helps with the springs.

The 1948 1949, 1950 and 1951-52 all model parts books all show the clutch sleeve as 66 3799, the mainshaft as 15 4260 and spring frame chaincase back as 65 7578.

The B series 1949-53 book shows the sleeve as 65 3873 with the mainshaft and chaincase back remaining the same part. So the sleeve does interchange. The mainshaft goes back to the 1930s.

The 1948 engine plates were different parts to the 1949 and later but I dont know what the differences were.

There is an address, in Bannockburn, shown under "contact us" but dont know if they have a retail counter.

They frequently come up on another forum, with new old stock parts.

PTFE tape is good - you can also twist it into a cord and use it in the recess designed for the string.

It would do no harm, and it is possible to get an airlock between tank and pump. Had one on my A10 after replacing the feed pipe.

Below from an old Payens seal catalogue giving their part numbers and dimensions.

If your engine is a swinging arm model you need the 1954 on crank seal.

The gearbox seal is an unusual top hat form and may be unique to BSA.

Devon red and BSA maroon are different colours.

The BSA lists show Devon red as code BSA code 34 and maroon as BSA code 37. That is from factory parts bulletin number 19 from March 1954.

Maybe not.

The TLS was fitted in forks with 6 1/2 inch (Triumph) and 6 3/4 inch fork centres (BSA and later Triumph).

I dont think C15 forks are wide enough to take it.

Not heard of apple green and dont think green was a colour option for B31 in 1954/1955.

Probably an attempt by a previous owner to align a wheel which could have been built with wrong offset , the shims behind the bearing would move the wheel towards the left.
