Early 80's Seattle Mariners Jersey legit???

[Eric1977]

Hello, I hope this is the right forum for my questions. I picked up this Seattle Mariners Jim Presley jersey yesterday and a few things didn't seem to add up. I know this type of jersey was the M's road jersey from 1981-1984. The year tag on the bottom right of the jersey says 82 (1982). Presley's first year in the bigs was in 1984, he was a mid season call up. I didn't know if it was possibly a spring training jersey from 1982, but the I turned it inside out and noticed that there was the outline of the #43 on the inside. #43 was worn by Gene Nelson a middle reliever at the start of 1982, but then changed his number to 24 at some point during that year. My question is did teams recycle jerseys? My thought was maybe with the Mariners switching their uniforms for the 85 season they just used up what they had sitting around?? Could anyone chime in on this and add anything to it? Could it be game used also? Thanks a lot! Eric
