Gunto Tsuba Seppa Habaki Interchangebility?

[Chako]

Hello all, I'm am assuming that standard military mount tsuba and seppa on a wartime gendaito blade are fairly standardized and interchangeble from sword to sword if the position of the locking clip hole is the same. I also figure it would be unlikely that a habaki off another gunto would slip on and not require some re-working of the saya throat for a decent fit. Are any of these assumptions correct?

Sorry about posting in the wrong Fourum initially. Thanks for any help. Best regards, Chako

Chako,

Seppa might need a bit of filing to enlarge the nakago hitsu-ana; ditto with the tsuba. Almost impossible to get the habaki from one sword to work on another; they are custom made to fit the blade.

Thanks, Grey, for taking the time to reply. I appreciate it. Best regards, Chako

I have a blade in type 98 mounts. Was toying with the idea of upgrading the tsuba with a cut out one (delux) one. Glad I asked the seller, as it was 2x the thickness of the one I planned to replace.

 

I tried adding an extra seppa, 1/32", to cure some rattle and found the saya lock no longer caught.

 

Not all that interchangeable IMO, despite being standard issue.
