All of my F 122s have a round circle in the end on the side, for the type of foot.
All M 122s are supposed to have smooth sides, and feet that fold out.
So what is an M 122 with F feet and a plastic back? 1390832 is the part number.

I think that's a transition model, but it's well-known. The real way to differentiate the M122 from the F122 is just the back panel or "pan".

It is easier to modify those first-gen M-122s to make replacement top case shells for F-122s, but it can be done with later ones, too.

On this same spur... What's inside this little jewel?

I haven't seen any 138xxxx part numbers that are M's (at least that I remember). Here's another with the same part number that has an F style back label

Very very early Model Ms had "bar code" labels.

I have never personally seen an F-122 whose model number did not begin with 611*

For sure there aren't many. These are from Cindy's haul for our MF project. There are some 139's, but those were the relabeled refurbs. I'm going to ask to see if they can pull a key and take a picture for giggles. Would be shocked if not an M, but it's certainly odd (at least to me).
