unknown marks

Regarding the “unknown marks” post I made on the 19th, does anyone know if these are pseudo hallmarks, or real hallmarks which mean something–I have exhausted all my sources, and NEED YOUR HELP! Thanks! Jack.

I guess that no replies means that no-one recognises the marks or has any idea whatsoever.

I sometimes think that posters must think us a bit stand-offish for not replying when the truth is that we simply don’t have anything useful to say, but of course a null answer is sometimea also useful…

I apologize for sounding so desperate…I guess others are having the same luck as I am finding these marks. Thanks to all who have viewed my posts!! Maybe between all of us, someone will eventually have the answer. Please forgive my impatience! Jack.
