I have two Spanish M43's which are in like new condition and identical to each other, I've seen several other's which look identical at gun shows through the years. All of these rifles have no makers marks/crests on the receiver rings. All have a dark park finish on the barrel/receivers, everything else is blued.. I can't tell if the receivers were "scrubbed" and refinished or if they were never stamped to begin with. Several years ago a dealer told me that these rifles were from a lot which intended as military aid that the Spanish didn't really want to talk about. Anyone know the history on this batch of M43's?
