One small correction, Chris. The stamp at the top is the Showa not Seki. Shouldn't change anything else about your blade, but it does put the probable age of the blade a bit earlier than if it was a Seki stamp.

Chogi Oil many different ones to choose from on that link.

You don’t show the blade, but the ones with the stamp are usually really well-made too.

Peter, Any stamps up higher, possibly under the tsuba/seppa set?

Here ya go, Peter. And thanks for the added photos! The stamp on the kabutogane, though can't see it well, is usually the "TO" of Tokyo 1st Army Arsenal

Yes, I've seen a few, not a lot, but a few blades with slogans on them over the years. SMR was the only one, to my knowledge, to do it on a mass scale. I think the rest are done on individual order. Posting pics of the one above for posterity

Not often you see an Army gunto with that flat ito style (there's a name for that). Also, the mon is one I haven't seen. Have you gotten it identified?

Thanks Smith! Just an update. We now have 400 Mantetsu blades on file. Nothing new to report, if you have been following this thread.

Well, David, no one has stepped up to help you on this one. So I'll make an almost totally uneducated guess for you (that should stir the pot!) Nakago has some darker patina, which usually means some age. I don't study these, but it's not as deep as the really old ones, so maybe 1700's or 1800s? Hard to say by just the old patina, though, as you can come across blades from the 1600s with almost no patina.

Hard to tell, but it's either Feb '44 or Dec '44.

The tsuka looks like a tachi (forgive if the term is wrong).

You got a good deal on that gendaito, Steven. It's legit.

I don't study these, so I cannot say. It's 1:45am in Aussie-land, so it will be a few hours before John wakes up and sees this. Of course, anyone with tassel experience could help out.

Johh, @PNSSHOGUN, will chime in as his day begins on the bottom of the world! Does the seller know that is a general officer tassel? Those sell for as much as a full WWII Type 98 gunto. John will have to advise on the fittings.

John, Don't know if you're tracking these, in general, or just on gunto you own, but I thought of you when I saw this one on a Mantetsu. It's got "727" on one side and some other kanji on the other. It's on a cut blade gunto for sale on this Buyee.jp auction

Another using the ">" as a 5, on a Mantetsu, found by @Ontario_Archaeology Matt at this Buyee.jp auction

OK, that was too much information already! Ha! Seriously, that’s a great photograph. Thank you.

Also interesting, the nakago shape is identical to yours, though I haven't surveyed other stainless blades to see if there is much variation. But the numbers were stamped differently, while the square is located exactly the same.

Thanks Mark! I have 22 stainless blades with numbers, now, all mumei except one. The hash marks are often modified Roman numerals. Not sure if that's what yours are as the numbers don't match the rest. Update: Browsing through those blades, I found the other square stamp. I seems to be different.

Hi Lance! Lots of good info so far. The style was a contengency model, designed in 1938, promoted for sale on the market in 1940, and really didn't become popular in the army until 1943 onward. Most guys call it a Type 3. You'll see all sorts of names, as it never got an official label. You can read all about it on the following links: The wartime type Gunto for army officers 1943 (Type 3 Guntō) (ohmura-study.net) History of the Type 3 Model Unveiling the Rinjiseishiki sword 1940 Once you've restored the tsuka ito (handle wrap), you'll see plenty of these for sale on ebay in the $900 - $1,200 range. The small stamp is the "NA" of the Nagoya Army Arsenal inspector. While not "traditionally" made, the vast majority of WWII swords were non-traditionally made, yet still attractive and quite deadly.

Mark, I have seen that stamp only once before, and for the life of me, cannot find where I've filed it. Yours has more detail, though, so I'll start a file with it. Don't know what it is, but being at the end of the nakago, my personal feeling is that it is a shop stamp of the whomever did the fittings. I don't see your 647 in my chart. Can you post photos of the full nakago, both sides, and an overall shot of the sword?

Hi William! I am the least knowledgeable person to answer this, so maybe the guys that know will chime in, but from memory, it seems a shirasaya will run you $700. Don't know who makes them. Wrapping a tsuka runs $300. There are likely lots of guys who do this, but the only one I've personally seen online is Chis Lohman here: Japanese-swords.com. Of the many likely guys that really know, you might try @Grey Doffin.

Thanks John! I have 3 others like this, though they are mumei. All 4, now, are stainless, kiagunto, and all 4 are numbered. I'm thinking it's a fittings shop stamp, but still unknown.

I have seen a good number of "immaculate" gunto coming out of Japan, and have been assuming they are full restorations, or new construction. The one at the top has a 1933 blade in it. Theoretically, the blade could have been re-fitted when the Type 94 came out.

Not to beat a dead horse too much more, as you're already returning the sword, but his upgraded fittings still don't raise the price of a sword like this to the level you paid. Top end - $2,400 "Hand made" - Brian already hit it pretty good, but this blade could have been fully made by hand, hammered and folded multiple times, even water quenched, but if they used a steel other than tamahagane, then it gets a stamp as non-traditional. Here's a list of the 9 ways swords were made:
