After much research, and not so much luck, I've been able to determine that Romanians don't really place a model number on their E-tools, and refer to them as "Army Shovels" or something to that effect. These feature a square blade with a nice tapered wooden handle, all held together with a heavy duty set of rivets. These are a fantastic multi-purpose tool.
A customer cleaned up his E-tool and confirmed that these are in fact Imperial Russian E-tools that were most likely given/sold to/or captured by Romania during the First World War or shortly thereafter. There's no telling what these e-tools have seen. I then chose to clean my up my example and found the same markings as pictured. Markings will vary though.
These were used from the mid 19th century still to this day (with some modifications) and these particular ones seem to have been passed along almost 4 generations of soldiers up until about the 1990s. If you have a WW1 or WW2 Romanian or Russian Impression, or any other of the many countries who used these, these are a must-have for your kit, I kept one for my kit as well.
I will include 1 Romanian Cold-War era "Ersatz" shovel carrier with these.
NOTES: These are all used, so expect wear, rust, nicks in the handle and blade, and potentially slightly bent blades. This is usually in the area that contacts the boot at the bottom of the blade. That being said, that's the worst I've seen so far, and although these are really old and have been used and abused, they are in really good shape. May or may not have markings. VERY limited numbers of these are available. Dates and markings will vary slightly.
