I have a dial lamp socket for a Grundig console that is very unusual and I don't recognize the base. It doesn't appear to be threaded, nor does it appear to be a bayonet type base. Can someone help me identify this and the type of bulb base that it would accept. I don't have any of the bulbs that came with it. See attached photos, thank you in advance.

Although hardly noticable, the pictured lamp socket is indeed (partly..) threaded. Please have a look at the small brass part which is bended over the edge of the socket. This brass part has inside a cannelure which matches a so-called E10 thread for small bulbs.

Two common dial lamps with E10 threaded base

7V 0,1A or 0,3A will match here. Please do not use too much force when screwing in a bulb, since the plastic base tends to break easily.

Thank you Bernhard! My next question is where can I get a 7V / .3A bulb, which is what I need? I can't seem to find them in the U.S. I can use a 6.3V / .25A if I need to, but would like to keep it original. Thank you again.

These bulbs can be found at ebay (eg. item #250956292938 or 350340792216), browse for "Skalenlampe". Somewhat cheaper to be ordered at reichelt.de:

They will ship worldwide. 10 lamps cost 2.80€, so it makes sense to lay in a stock of them...  Good luck!
