Anyone have info on F.A.B. Arms

[Biigg50]

I have an old F.A.B. Arms California Special side x side 410 shotgun.
I need to replace a couple screws and small parts. However I can not find any info or parts for these little guns on line. This is not Fabarms that is made in Italy but F.A.B. Arms made in Spain.
Are there any good sources out there for misc. screws for old shotguns like this?
Any info would be greatly appreciated.

I'd say take it to a hardware store, (with manager approval first) and find what you need. expect them to be metric threads.

I got nothing for you on this. I thought FAB was also Firestorm if that helps any.
