Thanks gents, I have been trawling the waterfowling sites out there also and came up with the same models, Zabala, Matador, also the Greylag which was converted and sold by Elderkins in the UK apparently.
Mike and Salopian, my next question is wondering what sort of payload did they throw? Is 3oz possible, or way too heavy?
-I take it if the conversions are a little marginal, they would probably not be throwing much more than the original 10 ga they were converted from?
Thanks again,
Karl.
Ps the Italian 8 gauge mentioned might be the 'Tonolini'.
