Thank you for the thoughts so far. From what I have read, at this grade, Beretta's 28ga uses the baby frame, but the 20/28 combination sets (and the 686 28s) use the 20ga frame.

The gun is new, but has been at the dealer for some time now. I compared it to a silver pigeon 1 or 2 (sorry, don't recall which) that had 30" tubes and no side plates to better understand what the extra $3,500 was buying. What I saw was better wood, and more importantly, engraving that appeared to be hand done or at least hand chased that really appealed to me. Gun was marked "bottega giovannelli" on the trigger plate.

While I would be letting go mostly older pieces, none are truly rare. I know this sounds like a rationalization. Thank you all for your patience.

Anyone know where to get the actual frame measurements for the 20 and 28 gauge frames?
