belgium FN parts?

[tom slack]

Hello everybody, I need some help finding left and right hammerless side plates for a FN belgium sxs shotgun. The gun was purchased for a double rifle project on the cheap. Hopefully I can find the parts or perhaps some one can tell me if other maunfacturers made the gun under license. It looks to be a mid wars hammerless sxs with a greener lock and ejectors. The gun is in good shape with no pitting and slight blue wear. The parts seem to be very similar to a L.C. Smith design. I saw an identical gun in about the same metal condition (except missing parts) and in 16 ga. (mine is 12 ga.) for $1798.00. Any help in identifying this gun and possibly finding parts would be greatly appreciated.
Thanks, tom
