Hi Dad -
I explain and explain, send photos - but you do not understand what I say. Please reread my last contribution, use a dictionary if you do not understand and have some history books handy.
Please read attentive - I try to be as simple as possible:
The spoon(s) we talk about was according to Ivanov made between 1908 and 1918 by ЕП and sold by Mr. Burg (even after the Revolution they were working??). The spoon is marked with the Latvian "local production" mark , in use after the foundation of the state Latvia in 1922 and the introduction of a new marking system for precious metals, the mark was changed several times until 1927 - then it was obligatory for whole Latvia.
Do you ernestly believe that the proud, just from the Imperial yoke liberated and souvereign Latvia would mark an Imperial spoon with "local production"? Please have a look at my last contribution, Imperial marks , Latvia under Russian rule, RM =Richard Müller - marked/rehallmarked by the new state Latvia with "foreign prodction". Absolut correct. Whenever you find a Latvian mark on an object it is from ~ 1922/27 on.
Conclusion: someone marked the spoon (wrong mark, wrong place, wrong time, wrong details) = fake. We collectors call this primitive kind of Latvian "local production" mark the "Polish mark", mainly used 5-6 years ago.
Your photo of Latvian marks, as usual not own photos but photos from some unknown "experts":
The text is wrong, the marks are authentic Latvian marks for "local production" from Latvia!

I think it is useless to discuss further - the material you show is anonym, wild mixed nonsens with much mistakes.
Collecting is a serious thing - you need technical literature, original objects, talk shop, a little bit brain - and do not believe there are no fakes.
Much luck!
