I'd always be interested to learn more about the oddity I got 
from Jim Taylor K9JT back in 2015, what seems to be a 33 in a 
tiny portable hard shell case: no paper tape.  Don Robert House
thought it was a model 33 compact.

Maybe I'm not using the right search terms, but is there
another one like it described anywhere on the internets?
