The shotgun your looking for was made in two models, Standard Grade and Target Grade. Both are a hammerless, takedown model, 6 shot, five shell tubular magazine, (you must tactically top it off to make it a 6 shot.) Barrels came in 26" to 32" plain, chocked full, modified or cylinder bore. 7.5lb checkered istol grip stock and slide handle. Made fron 1929-1933.
And the other is a Target model, Model 29T, has the same general specifications as the Model 29A, except has a trap style stock with straight grip, extension slide handle and vent rib. This model was discontinued in 1933.
I believe less then 3000 of these made. Good luck and Happy trading.
