Velocette MAC MOV 350cc 500cc Gearshaft Double Sliding Gear 22T + 19T Good teeth / Splines

This was kicking around at the bottom of a box of MAC parts that I’m clearing out. It should suit the MAC and Ali Mac. But I believe it may also fit the following: (Please make your own research before you buy)
MSS
Viper
Venom
Clubman 350cc (MKI and MKII)
Scrambler 350cc
Clubman 500cc (MKI and MKII)
Scrambler 500cc
Thruxton
Endurance

The teeth and splines are in decent, used, condition. A new one of these can cost about £150, so a little bit of use on this one makes it a very decent price.
