I did a few searches before the auction closed regarding Dick Marble. Several "specials" are attributed to him many are one of a kind. Apparently, Dick Marble loved the #3 as many of his specials contain the #3 the serial number.
Although the details may not be "all" documented by Factory Letter, they were made at S&W facilities by S&W employees. This is confirmed in multiple Factory letters. It would be pretty neat to understand the full history of Dick Marble and his "special" Smith and Wesson revolvers.
What was interesting, at least based upon the Letter / Dates is this seems to be the first 3" produced, by a number of years with a RB frame - one of one?
Upon request, RIA sent me a few extra pictures and answered a few questions regarding condition. The box listed the gun as a 4" not a 3" and that kept me away from bidding. Based on the additional pictures and answers from RIA the gun is in pristine condition.
I may be wrong but this one seems to be one of a kind. Is it worth the $4,500+/-? As mentioned, if the box had matched the gun I would have been interested...
