This was , as far as I can find, discounting Russia, the first slide-action European shotgun.
I remember reading about it, decades before the Inter-net existed, in Guns Digest and wish I could see, much less buy one.
I believe this is besides Browning and Russia, one of the few Euro pumps with a steel receiver.
They are selling now for about the same money, plus or minus, as they sold for decades back, if you ignore inflation.
I found that it was in production and use in Europe from at least the early sixties, and still exists, in some form, with the new name RS200 series.
