Hi, all. Just signed up today, and I've had a pair of M-Frames since the early 90's that I can't identify. I got them in trade from a bike shop friend who told me they were rare at the time as the lenses were smaller than most. Hope to post a pic or 2 soon...

Thanks in advance.

Here's a pic next to some M-Frame Pro's, with the Hybrid S lens for some comparison..

Thanks!

Dang. I don't think the pic posted.

The yellow frame has a "V" lens.

Nice pair

Yes, a V lens on a mix-matched frame. Could be a Mumbo, but unless you have a box or can compare the nose piece notch against a Blades, it's likely a Gen 1 M Frame.
