Here is a base shot of the three Russian pieces. These seem to be quite a bit older than the embossed dated models - maybe early 1900's? It might be hard to notice in the pics, but the pinholes on these are about the size of a Surge and the threads are very fine. Also, check out the vent drips on the inner skirt of the middle insulator. A close-up shot to follow.
