Tele-Raynox 135mm 2.8 preset

[Minolfan]

With an Exakta RTL1000 came an unknown preset lens Tele-Raynox 135mm 2.8 (T2, Exakta).
MFD is 1.80m now; at first the focusing ring appeared to be lubricated with epoxy at infinity. Aperture blades too much to count.
Filter 58mm.
Does anyone know more about the possible manufacturer, has some experience with such lens?

Almost certainly a T-mount lens.

Raynox is a distributors brand. Its still around today.

This is probably a very late preset type, could be mid-1970's or even later. No-name presets were sold into the early 1980's.

By that time there were many companies making cheap lenses, some are made in Korea.

It does not look like any of the "classic" Japanese presets of the 1960's.

On the barrel is written "made in Japan"; the export seal is still there, so I don't think its Korean. The T-mount can be changed.
Remarkable for me was the large filterthread with 58mm.
I had no idea that preset 135s were made in Japan after begin 70s.

At least an intriguing idea!
No 100% match there I believe.
