Not an "authoritive" answer, but
?
I have seen 2 FT-101F's in person (I owned one, but it was a parts radio - having been completely abused and destroyed internally by CB usage - fried the HV transformer and output section), and both of them had the same type of sticker (not embossed like the "E" models) for the Model, on the bezel above the VFO knob.
?
I sold off the chassis years ago, after having removed all of the boards, output pi network, knobs, etc. I may have kept that front bezel. I know I kept the front panel, because it is in absolutely perfect condition - paint-wise. I will have to check. If I did, I can take a pic. and post here, if there's interest.

Yes, I also thought this type of sticker was slightly odd. It reminded me of very early 101/101B (Non E). It was very similar to those from what I recall.

So yes, I think this is the way they came from the factory.
