I am trying to locate lenses for my Strant Leko 25/50 zoom instruments. I have multiple instruments with cracked lenses due to the use of a higher powered lamp. I did find that these instruments came out around 1996, but that doesn't help me find replacement parts. Also i am looking for the locking thumb screw and bump thing for the lamp base. A few of them have dissapeared into the black abyss.
