Original Lucas SS40 (?) headlight, brass,sound condition but needs some work, all bits except switch on the back. I paid £300 and would look for a similar sum. An item which cannot me made and very rarely found

Below is an interesting link, about a trip made in 1953. I thought someone might be interested in it - sent to me by a Sunbeam owner.
Kind regards to all.

Hello all,
There are some good shots of an MX100 outfit on holiday in the early 50's in this link.

Valve springs 1937
Dear Superior friends.
For My Matchless G8 1937 i need a set of valve springs. I have been told that they are the same for the SS 100.
Anyone know where to get them?

Hello, Can anyone tell me the correct length of the Sturmey Archer splined mainshaft please, as used in the 4-stud heavyweight 3-speed box. Many thanks, Nick.

Some may remember my recent appeal for a JAP F size spanner, to fit the valve coolers on AU. Mark Gibson very kindly helped me by making one exactly the right size, so my technical needs have been satisfied, thank you again (publicly this time) Mark. However the puzzle of JAP spanner sizes will not go away. Here is my collection:
Size E 1 9/16"
Size E 1 9/16"
Size F 1 7/16" (smaller than the E)
Size G 1 7/8"

The latest Ebay listing adds further confusion with a Size F measuring 1 7/16" only! All dimensions are across flats.

Do any colleagues know the secret of the JAP spanner sizes?

If you have a JAP spanner measuring about 1 11/16" A/F which is surplus to your needs I would be very interested to acquire or swap with any of the above.

Cheers,
Steve
