18 Karat Gold Earrings Need Origin and Maker

[bedzai]

I have a pair of 18 Karat gold earrings in an almost sunburst shape. Created by 2 circlets of 8 rods each. The weight is 7.5 grams each (15 Grams total) and bears the 750 stamp in a lozenge shape. One mark at the top says "2 BO". Another marks at the bottom is a downwards pointed triangle with 3 letters with individual circles around them. The letters are "R" and "M" and the last possibly "C", "O" or a small "d".
They have been acid tested positive for 18 Karat.

Does anyone know the country of origin of these marks? Age? Who made them?

Any help at all would be greatly appreciated.

Regards

Peter

Hi Peter,

They are Italian, from Bologna. The Italian registration number 2 BO was issued on the 5th Apri 1935 to "Guidi Oreste" di Piero Guidi, Via Malaguti 16, Bologna.

Your ear-rings would date to somewhere between 1945 to around 1971.

Thanks Trev for that awesome and quick reply! :-)

I confess I am stumped by the letters in the triangular mark that do not seem to tie up in any way with the name of the firm.

It would be good to hear a possible explanation if anyone knows the answer.

Hi Trev
I know the Swiss used RM at some point as a "Responsibility Mark"......Could it possibly have anything to do with that?
Or maybe a German "ReichsMarke"?

Perhaps a retailers mark?

The "750" within the lozenge is in the same style of the triangular mark with the letters R and M, and is a little unusual.
This makes me think that it is more likely that the triangular mark is that of the manufacturer and "2 BO" that of the retailer.
Just an opinion

As I am sure you are all aware, I have a very vivid imagination and a tendency to speculate wildly!

Following the fall of the Fascists many punch holders removed the fasces symbol from their punches, we have on occasion seen examples of this on the forum, is it possible, and bearing in mind the somewhat extreme positioning to the left of the '2' on the punch, that another number has accidentally been erased along with the fasces symbol? Is it just coincidence that that the slimmest of numbers and thus the easiest to be accidentally erased would be a number '1'.

'21 BO' was issued to Renazzi Mario, Via Clavature 2, Bologna.

Of course, as stated, wild speculation, and I'm more than happy to be mocked over the above!

Trev:

Funnily enough I had also been thinking about the odd spacing between the "2" and the "BO". You finding the Renazzi Mario makes me think it could actually be quite plausible. No mocking from me!

The hypothesis of Trev is very suggestive, but it must be stressed that, even if by mistake the number 1 had been eliminated from the punch along with the fasces, if Mr. Renazzi Mario had used it, would have committed an offense punishable by a large fine.
