What can anyone tell me about Dufa? I've heard the name, but never actually worked on one. I'm guessing 1920's? Not the most beautiful clock and absolutely dripping with oil, but it makes an incredible sound with those really long rods.

DUFA is (was) Deutsche Uhrenfabrik Etzold & Popitz. E&P began 1864 and declared bankruptcy in 1926. A brief history can be found in this thread. You could also slog your way through Schmid's Lexikon der Deutschen Uhrenindustrie 1850-1980, vol. 2, pp. 94-5 for the big picture. I agree the 1920's perhaps is about right for this clock. Interestingly, I could not find reference to the specific logo shown on your movement. A similar one is shown in the Lexikon and dated from about 1912. However, a message board search for DUFA might, I suppose, turn up something about it - certainly it will turn up a number of interesting threads.

Oh, DUFAs are swell, I have one in my working room which is a keeper and I've restored about 20 of those;
right now I'm working on a similiar model in a "baby" size.
Anyway - and I might shout this: Don't even think of cleaning up or polishing that dial. Those numerals vanish before you
even realize what's happening!
The slanted gong (often marked Largo Gong) has a marvelous sound when tuned correctly and the movements - usually with solid cut
pinions and graham escapement are a pleasure to work with.
The DUFA story is a bit fishy because it still is not known, whether they made their own movements. At times, there seems to have
been a separate movement factory owned and run by them. What is known to few is a cooperation with Gustav Becker and yes, G.B.
movements with the DUFA stamp do exist...

DUFA takeover by Kienzle was in 1930. The Deutsche Uhrenfabrik AG, a stockholding company, existed further on, after a part of the
company went down in 1926. It is said, that the DUFA AG. became a wholesaler then, which makes sense when thinking about the G.B.
movements they used.
A 1929/1930 DUFA catalogue does exist... and the brand still appeared in ads as late as 1932 - with a Berlin address, most probably
under Kienzle management.

The company, then named Etzold & Popitz, was highly innovative in case designs (Art Nouveau) around 1900 and it is said that they introduced the first round head tall cases around 1902.

Going back in history even more, see the winged wheel, the Flügelrad (usually: think Kienzle) they used as early as 1894:

So, I guess, by now you know that I get carried away with DUFA. Nutjob

The condition is nothing unusual. A lot of movements look like that and, to tell the truth, a dirty movement,
that stops, does no further harm. ;)
After cleaning, you want to check the spring barrels ans - most important - the stakings of the bottom wheels.
Not always, but it can happen, that they blow away after cleaning, when they are under power.

We will need photos of your clock to identify it further. DUFA used movements from other manufacturers at varying points during their time in business.
