Minolta MD Mount 135mm f/2.8 Celtic
This lens was optially identical to the 135mm f2.8 MD Rokkor-X but in a somewhat less sturdy barrel. The Celtic line was the cheap line Minolta sold to compete with third party lensmakers of the era. That was a pretty easy FL and speed for lens design so many manufacturers have great examples.
