14K SPG ? What does it mean?

[diggummup]

I have a pair of Pince-Nez glasses that fold into a monacle and date to the turn of the 20th century according to the name of the Doctor that is on the case. The glasses are marked 14k SPG and I cannot find out what that means. It seems to only appear on these types of glasses and I have seen others marked 12k gold filled SPG or 1/10 GF 14k SPG as well as ones marked like mine. Does anyone know what the SPG stands for?

The best i can come up with after a short search (i'm tired lol) is it's short for "spring".
Maybe they're spring loaded to pop out from monocle to spectacles?

(925) silver plated gold --silver base metal over plated with (whatever k amount) gold?

Could be one of these...

The 1/10 GF 14k means there is at least 1/10 of 14k gold if I'm correct.

The SPG I'm not completely sure but thought I've seen that with diving terms with glasses, something like submersible pressure or I've seen it with binocular lenses that has to do with the porousness of the glass but once again, don't quote me on that.

The "SPG" mark you are asking about stands for "Spring" which refers to the bridge which is spring loaded and provides the tension to keep the frames on the nose. This is why you will only see this mark on this particular style of Pince Nez glasses. Hope this helped.

Thanks. They look almost exactly like the one you pictured.

Okay after many more hours of research, i'm inclined to believe you. I cannot find any other refernces to SPG on gold markings other than on the folding type of these glasses. However, I cannot find any of them that are yellow gold either, only white gold or silver colored. Which makes me think- Could it possibly mean silver plated gold (spg)? Not trying to be rude, but I think the jury is still out on this one. Can you provide any written facts as to the definition of this marking? Thank you.

I did a lot of looking today and I have to agree with cracker. Just as spg temp is "spring temple" on glasses, so yep, I vote cracker has this one.

I just wish I could find a yellow gold pair with the mark on it.

Dano and cracker are right. Green check time.
