Hi Chris,
On my 1930 TT replica there is a BTH magneto marked TT on top. On the lower part of the side of the magneto body, the following is stamped in:
BTH (logo) TYPE Kcv50 A1
No 1F 307922
MADE IN ENGLAND
I presume that the magneto therefore is a Type Kcv50 (Whatever that means). It is a very good magneto.
Photos are available, but I have not yet mastered the art of putting them on to the SOC forum. I can send them by e-mail if you so wish.
Kind regards,
Carl
