Identifying a possible Makers Mark
Hello Members of the JAS-Forum,
I just joined the NKBKHK and im glad to now be a member. This is my first Post. Im looking forward to our correspondence.
I recently acquired a Tosei Gusoku and found what i believe could be a makers mark on the haidate. The problem is that some parts of the urushi have been lost due to deterioration.
Here is a picture for you: Maybe somebody here has an idea which katchushi or what maker school could be represented here.
Another idea i had is that it could be a numbering system in the context of a storage of munition grade armor.
Greetings,
Brandon

Re: Identifying a possible Makers Mark
Thank you very much! What could the purpose of the numbering on the haidate be? And where on the armor should i look out for makers marks. The inside of the dou maybe?Luc Taelman wrote: ↑Tue Feb 11, 2025 12:02 pm Hi Brandon, welcome in the Jas! What we see here is the number 27.

Re: Identifying a possible Makers Mark
Hi Brandon,
Firstly, a warm welcome to our forum! Please feel free to ask questions and share thoughts - we're all here to learn!
Regarding your haidate, as Luc stated (and you yourself have mentioned), the characters shown are likely an inventory number for munitions-grade or "shared" armour. Such armour - also called ashigaru was armour that was kept for use by any of the retainers in the clan and would not have had a specific owner.
Outside of the kabuto, menpo, dou (occasionally), kote (less occasionally) and suneate (even less occasionally), the other parts were very rarely signed. In fact, I don't recall ever seeing a set of signed haidate.
Hope this helps.
John

Re: Identifying a possible Makers Mark
Hi and welcome Brandon
I can agree with the above said.
What was left can be read as “二十七” or “三十七”. In both cases a number….probably for proper assembling/ storage…
Such numbers can frequently found on okashi-gusoku parts. Sometimes the dō can also bear a red inscription of the craftsman/ assembler.

Coincidentally this is not the first signed haidate i have stumbled across... if you are interested i can probably still procure the picture of the other signed haidate i have in mind.

Re: Identifying a possible Makers Mark
Please do share, Brandon! However, as already established the mark on this set can not really be called a signature, but is more an inventory number (which I have seen before).
