Pentax-EL 50mm f/2.8 enlarging lens
6 elements; 8-blade diaphragm; appears to be multicoated.
All metal barrel except for rubber grip; illuminated f-stops.
In original Asahi Pentax plastic bubble; appears never used.

Pentax manufactured lenses for a major enlarger manufacturer,
but this is the only example I have ever seen in Pentax brand.
Can you send my a pic for Pentax fans group ?
