Hiya,
I've discovered a few bits of long forgotten gear while clearing me house ready for a house move.
Among them is a spare strap, going free to a new home of its own.
I think its a Dimarzio one from the mid 90s or so - regular seatbelt material strap, but it the two clip-on leather ends which stay attached to the strap pins.
Yours if you want it…. destined for the nearest charity shop otherwise...
NOW GONE
