Ruslan just issued this correction to one of the brands. Here is what he wrote publicly:
"Dear colleagues! I want to correct my previous mistake: the brand "1 in the triangle" does not belong to the ABV 1871 (Liski), but 41 to the CAAB (Irkutsk). The error occurred because the investigation of this stigma was carried out by my friend who found the binoculars with this brand and looked at his form in the repair record, considered that it belongs to the first record when there were two such records. And the repair date corresponded to the second record. But I told the first. The information was sent to the publication, and at that moment everything appeared and there was nothing to fix. Accordingly, the question of the belonging of the said emblem is again "frozen". And in the winter of 2014, I had to go to Iruktsk for 109 ars, where I investigated, including the issue of this arsenal (in the past 41 CABA). What was my surprise when the master of the OTK of the workshop on small arms repair told me that their brand is "1 in a triangle", and it is at this same time that they stencil on boxes with passing weapons. Later it was also pinned to others, in a documentary way. In general, this "1 in the triangle" - 41 VABA (109 ars GRAU), Irkutsk."
