Unknown BSA Bits

[jelo68]

Hello together,
i buy a lot of BSA-bits and there are some i cant assign to . The maroon  Airfilter fits on my A10 plunger but it looks diferent to the Partslist .
And I get some Forkslider whitout Numbers.
Can someone tell me where it is for?

The maroon filter is the early version which fitted the long stroke A7.
The others are the later version which has the right angle rubber connector.
