Identifying TO-3 w/HP house numbering

[Curious Marc]

Forgot to mention, I have a 2382A that works (affectionately known as the "Munchkin" terminal). I could measure some stuff in mine for comparison if that could help out. 
For the HP curious, the 2382A makes an appearance at the end of one of my videos:

It is very cute (I think) ;-)
