What I like is that these appear to have never been refurbished. I'm curious as to the ding in the SVT-38 scabbard. It looks like it could have (maybe) been struck by the base of a bullet (i.e. a tumbling round deflected off the ground?), but that's speculation purely on my part.
You were indeed lucky to stumble upon these bayonets, especially the SVT-38. I have one that was gifted to me, but the muzzle ring is cut off. I would like to ask if you could provide for me some measurements of the cross guard: Height, outside diameter of the ring, and width of the "skinniest" section under the muzzle ring.
Rusnak, this is the best I can offer for now. In each photo I tried to line up one edge of the guard with an even factor of 10, with the camera positioned to capture the measurement at the other end. So for the overall length of the cross guard, the left side is aligned with 20 inches, even though it doesn't look like it, so that the camera can show where it falls on the scale. Careful measurement shows an overall length of 2 & 1/4" (to include the slight rounding of the outside surface of the crossguard).
The other photos align one edge on the 10-inch mark to show ring width, length from the edge of the blade to tip of ring, width at the waist of the ring extension, and overall shape of the ring extension.
The ring-width photo is not very good, but careful examination with the eye and tape measure put it at 3/4" outside diameter exactly.
From the edge of the blade to the tip of the ring measures 15/16" precisely.
The narrowest part of the waist falls midway between 5/16 and 3/8, so about 11/32".
