Pangaea, and Shorty McKenny have both out bid me on guns recently. Shorty for sure has been having a run at the USFA guns with some deep pockets.
Last Colt I bought was a new Colt with 4 3/4" nickel, Nutmeg once piece ivory, unfired and in the box with a factory trigger job. Cost was $1800. That was last week on one of the gun sites. So still some reasonable guns to be had at decent prices if you look around.
New nickel Colts have been selling for around $2k. Jim's ivory is $600 plus $100 in shipping. Trigger/action job if it is any good is likely worth a few $ and again some.
I get it about the Sparrowhawk. I'm just not that kind of collector I guess.
