If anyone is interested, Image Communications in Bedford Park, Illinois has some of these lenses available. They were originally part of their Epitome Accessories listed as "Lens L-11 Plastic Deflection 10 layers 10"w x 3.5"h x 5.5" Overall Height". There is a tiny picture in their catalogue that suggests it looks like a 2308 lense. I called them to find out if they still had stock available but unfortunately they don't. HOWEVER ,They now carry the L-10 lens which has nearly the same dimensions (which I seem to have misplaced). In any case, if anyone is interested in a set, they are $9.00 per lense. I don't know if Image will sell to the general public, but I still have an account there so I'd be glad to be of assistance if necessary. I beleive that they also have a $50.00 minimum purchase.
