Hi
I have a lot of 7 clusters, one of which bears the D.R.G.M. logo and which is the most modern..
The remaining 6 date from the 1920s circa made in the USA bearing the trademark "BENJAMIN".
Please consult the 3 pictures if attached and contact me if you were still interested in such items...
Indeed your ad is a bit old and it may be that your interest is no longer relevant...
Best regards
