OWD, I have a cased Charles Lancaster 'A' or Best SLE 12 bore mfg. in 1924 with 29" barrels and the Mount St. address, and IMHO, it compares with any London Best I've seen or owned in quality except maybe Boss. 14,4xx S/N, chopper lumps, wgt. 6 lbs. 6.5 ozs., with original 15 1/4" LOP stock and handles very well. I think they went out and were absorbed by A, G&L in the early 30's. I will post pictures if you can tell me how to do it on this site. Best, Sandlapper
