Are the grips number matching to the gun? They can only be correct if the gun shipped between ~ 1918 - 1920. Which I think they are because it has no logo on left side of frame. And that's the only period the Reg Police grips had the gold medallions. After 1920 to 1924 the RP grips had no medallions.
Before that and after 1923 it came with two screw target grips.
So if he parts it out, the pair of grips is worth ~$150 by itself.
Now that it didn't sell, the seller might be more negotiable to an offer.
• "No-Logo" guns from 1917 and following WW I until gradual re-use on all model, I, K, & N frames by 1920/21.
• Prior to WW I, .22/32 Heavy Frame Target models were supplied with two screw extended target stocks as standard. After WW I the Reg Police stocks with notched back strap became standard. By ~1920 all stocks including on 22/32 HFTs, changed to rounded, convex stock circle stocks w/o medallions and rounded, convex stock circle target stocks w/o medallions as optional until 1923. Above serial number ~258000 (right after WW I), the standard HFT's stocks became Regulation Police stocks on a rebated grip frame, at first with deep dish gold plated brass medallions in the late 'teens. Checkered two-screw extension target stocks with gold plated brass medallions in 'dished' stock circle tops were optional until 1920, w/o medallions after that. (see "August 29, 1923 change" below).
• Aug. 29, 1923 change order, replaced .22/32 HFT's sq butt RP convex top stocks, returning to 2 screw target stocks as standard but with convex tops, and w/o medallions. And from the original Paine bead front sight w/U-Notch to a Patridge w/square notch rear. The next day, the same was ordered for the 32 & 38 Target Models and the Single Shot Model as well, S&W 1857-1945 N&J pg. 235.
