This lens had layed around my junk pile for years with a badly separated front group. The other day I repaired the bad front but the back lens has a big gouge that nothing can help. It is an early waterhouse type. Showing Wide open and f25 (home made stop)
Thanks. I figured that Model A could make even me look good! It was on purpose. Who needs a $3500 Pinkham when a $5 old brass Sci Lens Co WA will do the job?
