I need the rear "eye piece" for one, not a K4 A, an early non centered K4. The glue in the lens set is bad.
Or if anyone has a lead on a K6 let me know.
ElPaso made K-4 and (less frequently a K-6) comes up for sale on the classifieds....prices run $150 give or take and unless the one you have has sentimental value, you're best off just replacing the entire rig.
I've owned my K-6 for 52 years now and it's still as good as the day I bought it.....and I got it used....they are a classic worthy of anyone's hard earned cash.
Check with Larry Weiz about repairing or replacing your lens. Very helpful and knowledgeble and reasonable prices.
