Re: 1955 Match Target Pistol 6"
From your serial # you have a Match Target Woodsman model cal 22 LR made in 1948.
cdnninvestments.com in Texas has mags for $20 ea.
Price depends on actual condition, geographic market, and whether you are selling to a collector, a user , or a dealer, and how fast you want to sell it. A 98% pistol will likely fetch about $1000 tops. If you find a dealer with good traffic who does consignments tou will likely get 80% of sale price.
