Marksman 0035 pellet rifle

Sorry no. The entire rifle is $80 on Bakers, he mightr have a spare part for a ???
Should be a SR/Beeman and many used the same sights & screws ( & 34 coil spring, at least sometimes). I'll bet the same sight is still on something currently selling tho tiral & error might be hard.

You wouldnt happen to have a good picture of the old one? Some idea on height above receiver block?

Good luck,
John
