SaxonPig;
Like you, my experiences with internet auctions has for the most part been favorable. In this case I too have decided to accept it for what it is.
SaxonPig and KKG;
Personally, the suggestion of removing the hammer block to improve the action of a revolver, has never been made to me. Moreover, it defeats the purpose for which it was intended and I know we probably all agree that to do so, would be foolhardy. I'm not suggesting either of you agree with such a practice or advocate it, just that, as you say it was a common "thought" that may account for discovering missing hammer blocks, such as in my case. I can say with complete conviction that such a practice would have raised a few eyebrows in my circle of colleagues. I have little doubt it may have been a popular, though ill advised practice and could have made some improvement in a rough action, whether real or imaginary. Weighing the trigger pull is generally accepted as the method by which one could determine if such a practice had any real effect. But doubtless, the fellow who would remove a hammer block to improve or correct a rough or heavy trigger pull/action, in all probability wasn't doing that. There have been a couple other "kitchen table" methods, with which, I'm sure you are both familiar. I will not repeat them here for the consumption of those less experienced who might attempt such shortcuts. The majority of these amateur quick fix action job concepts, usually resulted in either a revolver that failed to fire, fired unreliably, or was prone to accidental discharge. Bottom line, especially for the forum guests who may be reading this post, the hammer block is an important safety feature and should never be removed.
Mike, I did not receive your email, but my thanks for your kindness just the same.
Bill;
Congrats and thanks for sharing that information.
Edited to add:
By the way....I'm beginning to reach the conclusion that the hammer, mainspring stirrup and possibly the barrel and cylinder are all modern(.c1964 or later) refits. I'll be posting that in the S&W Revolver 1945 to Present section, as is appropriate, if you guys want to follow up with me. Thanks again for all your comments.
