Sighting of an old Adler on a shelf

During a trip last week, did a stop-off at a local thrift shop. On a shelf were a well-used Hermes standard and an old Adler. That Adler was surprising; pre-war machines rarely show up in thrifts stores anymore.

The decal on the cover was in great condition with cover-nuts present as well as original spools.

 

This may actually be a pre-pre-war machine; the serial number was I think 4-digits and that'd make it a pre-1914 specimen. (Serial number 6639 ? -should've taken a better picture.)

The drawband was disconnected (still present) and one keylever had been mistreated (bent?), but overall the machine looked complete and rustfree. The nickel should polish up fine, and the wide ribbon looked usable too.

Overall a decent machine with lots of potential to be a very fine ancient typewriter; at 45 Euro an entirely reasonable asking price too. (Left on their shelf :)
