The top picture.... the one with ser # xxxxxPZ211 was made in 1981. That gun is of Japanese Manufacture.

The middle serial numberd gun (pic 27 I think) was made in 1967 and is in fact Belgian made.

The final serial # picture gun was made a year later in 1968, and also in Belgium.

The belgian guns "tend" historically to bring a higher price tag, and most of that has to do with the type of guys who historically used them.... older southern guys.... who having seen the Japs bomb Pearl Harbor want nothing to do with anything made in Japan. the Jap guns are made every bit as good and perhaps even better than the Belgian guns. Market trends as of late, Jap made guns with factory installed choke tubes have been bringing in the most $ (especially 20 gauges).

We could throw #s around on prices, but its hard to tell with jsut pictures... it looks like one of the belgian guns has a replacement stock on it.
