1970 A65 Firebird

[Ian C]

Title is for my latest project. This bike was repatriated from Illinois so I assume it is an East Coast model. I know that the LH sidepanel should have the standard 'Firebird 650' transfer, but the RH sidepanel has what I believe to be, a unique for 1970 'BSA' transfer. Can anyone either help me to identify the font or point me in the right direction of someone who could sell this transfer? I know my bikes sidepanel had this BSA transfer originally as I can see the faint outline on the panel in the paint.
