I have an inventory of colortran lekos that I'm trying to fix up/maintain and the barrels over the many long years have been changed to varying degrees, 2-3 times per year over the past 25 years I'd guess. Because of the age and use, many of the lenses in the barrels have nothing to cushion them from banging around in the lens slot causing chips and cracks, etc. Anyone know where I can find replacement padding of some sort to keep these poor lenses from breaking?
