Hammerback,

That is a very nice model 21.It is a standard grade model 21, 20ga of the late fifties. Price in 1955 was $390.00, the vent rib was an additional $90.00 and the 3" chambers were $15.25 extra. If it has a pad that was $7.00 extra.

Your sn of 30521 is 1000 less than my 21 20 which is 31521 which I order in 67 with 3" chammbers. Price was $1000.00 and $25.00 extra for the chammbers.

Last Sunday there were four 21 20's in my duck marsh all using TM 5's 1oz.

Enjoy AWC
