I found this ad Asahi Pentax spotmatic | V
It says 400 mm tele but nothing more.

Can someone tell me what lens it is and what is it worth?

The lens is a preset 400mm F/6.3, M42 mount. I'm not sure of the maker, but it was sold under different names. Mine is Mamiya-Sekor.

It has 3 lens elements, non-coated, is cheaply built; IQ is terrible (at least my copy). It's long but not heavy (there's not much glass in there).

The lens is sure fun to play with, but I would not pay more than US$ 30 for it.

This is it: linky.
