I picked these up recently on Ebait. They're old enough that they could be difilm construction (paper and polyester dielectric).
But no 4PS, 225P etc type identification. Measure nuts on spec, .102, .104uF. In my experience that's not too common in +40 year old orange drops, must have ben stored properly so they didn't absorb any moisture.
Note the outer foil mark is two "M" that look like the Mallory M, instead of a bar. Not seen that before.
What Type of Orange Drop??

That's "M/M" because they are really M&M caps, orange M&M's! These are known as chocolate drops!

Can tell you for sure that the circle 2 is a SPRAQUE part not Mallory
I too have not seen the double MM

looks like a Motorola M or logo or part. they use to supply parts like you might sometimes find resistors in a glass tube for the radios etc. I think, like many things Mallory or Sprague may have made the part for Motorola?
but just guessing.

Re: What Type of Orange Drop??
Never thought of that, it does look like the Motorola M.
I think the circled 2 means Sprague made it, so maybe it's an early 220P or 4PS without the name on it made OEM for Motorola?
