Sorted Shimano front mech cable clamp

[JimK404]

ETA: typically, I found one about ten minutes after posting.

Sometime in the last 25 years the cable clamp nut & bolt fell off the FD-M563 front mech I'd now like to use for a pub bike.

I think it's Shimano part fd-3500 - does anybody have one going spare, maybe from a knackered mech? I can't find one for sale for less than the mech is worth.

Thanks!
