Tks Woks.
It's an ebay purchase from USA, so sent an ebay-email to em, can't attach pics to that, but put my email addy in the note, hoping they will contact me that way then I can maybe sort it.
It's supposed to be a bigsby bridge but unlike the sorkin it has no branding anywhere. more like sold a $10 dud for $50.
Cheers PK
