1979 Mame-Tan50E brochure from Japan,
three pages. Click to enlarge.

be a fourth page as well with the specs, but I could find only
these three pages. The print month and year usually appears on
the last page of the brochure so I can't be absolutely sure that
this is from 1979 but the model with the cast wheels came for
1979 so... |
