Thank you posting an English version of the article by Igor Robertovich Karklinsh. My 1st reaction is to say he should go to Liege, however, after taking another look at the pictures, I feel he did. He should have made use of the resources there. With two museums there are many brains to pick!
I could spend months going over this article, but it is not worth it to me. One of the most glaring mistakes is his references to the 1894 expo. He states that Lebeau died in 1896. So, is possible he was too sick to attend? Also, take a good look at the names. These are the same makers who formed the consortium that became FN. LeBeau was never part of the group.
Having said all this. My heart goes out to Igor for setting out alone to uncover this info. Is he still around? Does he speak English? He would make great addition here and I would love a session on Skype with him.
