Thats a very nice package indeed. Does the 5.5" barrel have the extendable front sight? My 1961 vintage model has a serial# 294XX. I would guess that your's may be a late 59ish model, but Tom Beckwith would be the person to answer that for sure. Does the box for the olympic weights have anything printed on the inside lid?, are the weights steel or maybe the very rare aluminum??. Very nice set, good luck on your quest for a field barrel, I would like one as well but they don't make an appearance very often.
