What's with this Shattuck (World of Lugers) guy, anyway? In trying to access his inventory several weeks ago, I noted that he wanted my credit card number. I emailed a question as to whether he charged just to view his inventory online, and he responded that he did not. Then I tried again and still couldn't access without credit card. I followed up with another question as to why he needed a credit card if there was no charge to view inventory - and for that matter, why he needed a credit card number at all if the buyer was going to pay by cashier's check. He must be an old curmudgeon who's tired of fooling with me, 'cause he didn't respond, but at 66 and counting, I can be something of an old curmudgeon too...so he sure as H___ won't ever hear from me again!!
As to others mentioned, I've been collecting over 50 years and have purchased from several of those listed in recent years - Adams, Bessler, Brocks, Checkpoint Charlies, Retting (several purchases many years ago), Ricky's, and others - and share the observations, irritations, etc. mentioned by others above as to lack of photos, very cursory descriptions, etc. on websites of some dealers. I am especially aggravated at being unable (for technical reasons - probably at my end, not theirs) to access online photos of the good inventory at Bessler's and Ricky's websites. Of those I've dealt with, I wouldn't accuse any of them of OVERdescribing their guns, but don't think any were guilty of serious misdescriptions, either. Certainly never returned a purchase to any of those, and was pleasantly surprised with several of the acquisitions.
In addition to WW2 small arms, I'm also into Civil War guns, too, and I've found that, in general, dealers in quality CW arms tend to describe their wares more fully and more accurately than WW2 dealers. (Of course, CW guns tend to cost quite a bit more than most WW2 arms, so that is probably understandable.) Some dealers, like Joe Salter, have a substantial inventory in both genres, and two of these are not already listed above - davidcondon.com (several purchases from him; good dealer) and horstheld.com. I sure wish somebody could have furnished me information like that set out in this thread several decades ago, and hope my comments will be helpful to younger collectors.
