Pendant Ceiling Lamp

I bought this pendant ceiling lamp from an architectural salvage place in Adelaide. The seller thought it might be as old as 1930's, I have no idea.
The bulb holder is for an Edison screw E27 (still a common standard), and was marked with the initials DRGM, which might be Deutsches Reich Gebrauchs Muster. It is made of brass and ceramic. But the ring that holds three of the lights and the central rose both have plastic fixtures that clamp onto the wire, stopping it slide (see second pic). Does this suggest a more modern provenance, or might it have been added later?
One of the four shades got a serious ding, and I am hoping to repair it (see third pic). I am torn between using Ultra Clear Araldite and a proprietary product designed to repair car windscreens. Any thoughts?

 

Not much of a clue on this since not American. Think the plastic parts probably point to post WWII since not bakelite. Maybe lucite? I am not familiar with the product suggested for repair. Would think some kind of clear epoxy would do the trick.

 

it could be older than 1930s and made as Neo Gothic which was a subcategory of Jugendstil on the continent. refurbished with new electric parts; cable holders could either be glued or cold welded on the main ring.
BUT... it could as well be made during one of the many revivals especially in the 60s.
the DRGM is no indication of age anymore; first of all the Americans stole big parts of the archives during and after the war; and then there were also some shtroonzes that started to re-use it as deceit.

 

Your rather nice lamp is probably older than the 1930s, but could be as new as the late 1940s. (during that period nouveau met deco while also remembering a&c/gothic revival). There was most likely a brass chain intertwined with the electrical cords holding the individual lamps that somehow got lost during the rewiring when the plastic bits came in. The glass globes are themselves not rare or valuable so feel free to experiment. The central one usually was bigger and a little more interesting, so if it doesn't work, the replacement doesn't have to be the same.

 

The fixtures that hold the wires tot he ring (and the rose) are soldered on, I'm sure.
Anyway, I kind of like the ambiguity, anywhere in the last century, right?
I love the word shtroonzes! I must practice getting that into my conversations.

 

Thanks for your further broadening of the possible age of this thing, bigger mystery!
The brass chain you mention is intriguing. Was that because the copper current-bearing wires weren't considered strong / reliable enough? And did they use it to get an earth connection down to the metal parts? I suspect they weren't bothered by earthing, but now a two core wire is a suspect thing -- how are you going to get an earth connection?
And the news about the central globe / shade is interesting. If they usually had a larger central one, then all four must be replacements. All in all I can relax about fixing the broken one.

 

Aralide is Limey speak for epoxy, so we are on the same page.
I will investigate lucite, to see if it could be what I have, cheers.

 

practising "shtroonzes" is best done entering a posh Italian restaurant.

 

I see that the rings are soldered, but I'm not saying it is older than the twenties. Also, could be a marriage (less kindly termed Frankenstein).
The rings (which would otherwise be unnecessary) on the individual lams points to the chain. It was never considered a good idea weight down and stretch the cords. And no, no earth. You can attach a wire to the frame if you like. Won't hurt.
Here's a typical example of something totally different yet somewhat similar.
