Middle 2 are Short Tang Deluxes....
Bottom is a 1937 Long Tang Standard...my favorite....
I read the occasional $500 dollar 71 but here in the northeast they go for 2500/3500 for mint short tangs and a mint 1st year 98% sold for $4600
Ones with "extra holes go for 1300 to dealers asking 1700....
Can't wait for thee first week in Maine this year....then back to NH
