Does anyone know who does sight repairs for Lyman Rear Sights? I have a Model 57 for Lee-Enfield No #4s that I got on E-Bay that I think the quick release for the elevation slide is messed up on as it depresses but doesn't release the slide from the base and neither does it allow the slide bar to go up or down when the elevation turret is rotated.
Thanks in advance for any assistance.
