A collection of D2s in the making

Good morning all,

A friend of mine and I have started working on these antique machines.  My friend has acquired 3 D-2s - a 1939, 1941 and 1956.  He also has a D47U (I think, that one is still on it's way to his place).  I recently purchased a D47U that we have to rescue from it's current resting place.  In the meantime, we saw this plate on the back of one of the D2s and thought it was interesting - I'm not sure if it's rare or common - any thoughts? [attachment=73530]20230829_193934.jpg[/attachment]

they all had that at one stage. many of the tags got lost overtime but for a number of years every machine had that tag ex factory.

Great thank you, it's the first one that we've seen. Going to attempt a rescue of a 4d-7u tomorrow. Will start a new thread with pictures.
