What you have is what looks like a Remington 17, or the precursor to the Remington KMC.  From the round hole under the type bar guide, I know this to be a pre-1946 Remington.  I've serviced many of these--including one used by the U. S. Navy during World War II.  It was painted a kind of hammertone silver.  I even fixed one that had a broken spring drum band by substituting a small gold chainmail purse strap!!  It worked.  I have in my own collection a 1939 model that has little trap doors where the ribbon spools go--yours may be just a little later built than mine--possibly the same year, but I would imagine something built in 1940 or later.  What is the serial number?

I have a KMC, and the serial number for that model is found by removing the rear panel. Just pry carefully at the top center of the panel, right below the carriage, and that panel should come off; it's hooked on at the bottom. The serial number is stamped about halfway down (facing away from you, as it happens). Presumably your 17's serial number is in the same place.

That's interesting about the serial number location.  On English KMCs, the serial number is under the carriage and usually begins with 'EJ'.
