Guns and Ammo has a special edition magazine on newsstands now under the title Surplus Guns. It has a couple of good articles in it by the inimitable Garry James if anyone's interested: one on the Smith and Wesson 1917 and one on the Webley Mark VI.
Be aware this is a reprint from earlier magazines. If you have the older mags check the articles before you buy to make sure your getting something new.
I picked this up yesterday, and read the M1917 and Webley articles this morning. Not packed with information, but decent overviews and some nice photos.
