Sweep- you'll have a long hard look for that book by Roger Rule. Try Collector's Firearms on Fondren Ave. in Houston for starters-I read all the ads in Gun List-have never seen a copy. Did find one on E-Bay at $750.00 My offer for me MINT second edition at $400 plus $25 shipping insured stands to you ONLY for 30 days. Advise by PM if you are interested. The .375 is very desireable, the .358 scarce as hen's teeth- but I have a G&H custom on a pre-64 action in .35 Whelan that is a nice "split" between the hard kicking .338 Win Mag and the much better .375 H&H Mag. If I didn't have the .35Whelan (and I get Rem 100 grain Core-Lokt shells around $25.00/box locally) I might be tempted to make you an offer on that .375. Be very careful of the "wolves in sheep's clothing" at gun shows- more hucksters there than at a P.T. Barnum hosted Friday night poker game-- RWTF
