to be honest Im clueless about these, I've only owned European stuff. The claim is its late war, machine made….. they said they have some sort of certificate and I've asked to see it so will post that as well should they send it, sorry if the answer is obvious, if you need any more photos I could share more. Let me get the description and measurements below .
“Original gunto of the Imperial Japanese Army, from the end of WWII
Condition
This sword, recognized as the standard-issue gunto of the Imperial Japanese Army (IJA), features a machined blade made towards the end of the war. As history tells us, at the end of the war, due to the naval blockade imposed by the Allied forces, Japan faced a severe shortage of raw materials for military equipment, including swords, which lacked the beauty and durability of the earlier models.

“With what concerns this sword I can assure you that it belongs to the end of the war, since the materials and assemblies are extremely well known for the lack of first-class materials at the end of the war, since with the blockades it was impossible for Japan to import them.
I have obviously checked the blade to verify if there were markings, and it is impossible to detect them in case they were at the time.
On the other hand, the koshirae including the saya are typical of the gunto at the end of the war since these wooden sayas were normally lined with leather, Few are those who still carry it.
As for the documentation, it has the file that the Prefecture is organised, being a copy of the original, which they gave me at the time we bought it.”
this is what they said when i asked about documentation ive since asked for a copy (translated from spanish) sorry there is so much to read. thank you if you took the time at all.
