Sorry about the wrong date. Its not a field gun, or at least not what I've read on the Fabarm field gun of that time. Mine is only 27 - 1/4" long while the field gun was 28". The only barrel I can find in the 27" range is the skeet barrel that was part of the set. Its kind of a mystery to me. I can't find anyone so far that has one of that age grouping to compare it to.
