Barrels are probably 27-5/8"? I have an Erbi boxlock 28ga with DT, PG, splinter, metric 28" M/F bbls, coin finish frame with some decent engraving, pretty plain wood, but nicely fitted. Gun originally had sling swivels, so probably for the Euro market. Can only guess what the "English" on yours designates. Mine's a decent little gun, close to quality of current AyA 4/53 but not quite that good. Erbi went out of business during the Diarms fiasco of the 80's (check my dates). Weiland has very brief mention of Erbi in "Spanish Best."
