CSN, last night I checked GB completed auctions for the model 27-2, 6" models in what appeared to be in equivalent condition as described by your friend. There were 3 examples, 1 nickel plated sold for $971 with unmarked blue box, 2 blue examples, one with presentation case & tools the other was gun only. They sold for $900 and $874.69. These were all recent transactions.
Today I went gun store hopping. One shop had two mint condition model 19-3's with 4" barrels. One had box and papers that I could see, and the other was gun only with smooth target stocks. Both were priced in the upper $900 dollar range. Both were on consignment, so prices are probably negotiable. One shop had a 4" 686-3 that was priced at $799.99.
