NOS pony keys or?

I found this artifact in my closet of parts with the intent to have one of them cut. I bought a long time ago say at least 10 years from some key shop in Ohio I believe. Not that it matters, but intellectual curiosity drives the question: nos or not? I take it that the rectangular head means ignition key while a key with rounded ends would be for the trunk? (So both are ignition that I have it would seem.)

Period correct OEM Ford keys typically have an 'H' stamped on them.

Appears to have. Thank you for that detail.

The "H"

I had one of my "nos" H designated pony keys cut using the original Ford key as the template and it won't turn in the switch  I looked at the cut job and it is spot on.  I am surprised that tolerances on the ignition tumblers are that refined.  I will bring it over to the key cutter and they said they would take a look.  Thank you everyone for your observations.

Try pulling the key out of the tumbler a 1/16 of an inch and then turn

Some where I have about 10 sets of those left that I bought about 35 Years ago when I owned "TALLAHASSEE MUSTANGS, Inc."
