No, Belgian guns have to be examined on individual basis. Obscure Spanish stuff belongs is a dumpster. I have examined 2nd-hand 871 in excellent condition. The gap between iron and wood was large enough to see part of the ej kicker and two halfs of ejector rod were of unequal size, so if one breaks both would need replacing. Most of that good looking obscure old stuff was assembled and finished by hand so parts would have to be made to order. Why pay for parts and labor in excess of what the gun is worth in the first place. That route seems appropriate for stupid people only.
PS. The chance that Eusebios piece will be a dissapointment are better than average.
