Arsenal marking on Type 32 cavalry sword

[Ben123]

I recently bought this nice type 32 and I was wondering if someone knows something about the marking on the guard. Also Is it possible to date this kind of sword. I know that type 32 where made between 1899 and 1935, but is it possible to precise the date.
Serial num: 025545  Type: ko 39" long

Hi Ben,

 

The stamp on the far left looks like it might be a Kokura Arsenal control stamp (post-1929 use per Fuller & Gregory's book). That seems late for the serial number. But it could also simply mean the sword was returned to the arsenal at some point for refurbish/repair and marked then for inventory purposes. Not recognizing the other two. Maybe some others can chime in? 

 

Is your blade 32" (Ko) or 30" (Otsu)?

It’s a ko 32" the finger loop is broken.

I wouldn’t be surprised if it was refurbished/ or it’s a late version because there is a finish on the blade (see pic) and on the scabard.

Those leather finger loops apparently didn't hold up too well on active duty. My understanding is that when the swords were returned to the arsenals for refurbishing, they usually removed them and plugged the hole with a steel rivet. (My Type 99 Otsu got that treatment). 

 

Nice looking blade! You don't see the Ko's nearly as much as the shorter Otsu's.
