Help With Remaining Two Kanji

[Ed]

Hi Guys,

I have what may be the smallest tanto ever made!  Kidding, I have no actual proof or claim to that, but it is tiny with a 3.5" nagasa.

 

Part of the sayagaki has given me problems for years. It is in three sections.  The top section was never a problem, it reads Mumei Den Osafune Kiyomitsu.

 

It was the middle and last section which had me stumped. 

 

At first I thought the bottom section was the date, however nothing seemed to matched.  Then I assumed it was the length as you can clearly make out 9 bu.  The top character of the third section is also clearly NAGA, as in nagasa, but again the second character doesn't fit.

 

After scratching my head and checking various resources off and on all day, I decided to enlist some help.   Spoke with our up and coming star, Ray who was kind enough to take a look at it.  Man, am I glad I did, with a bit of research on his end he determined the last section was indeed the length. Turns out he had seen a couple of things I was unaware of. First, Nagasa is sometimes truncated as NA (長).  Secondly, the second character which evaded me (弍) is a more official variant of the number 2.  So, that completes the bottom section Na 2 sun, 9 bu arimasu.  Voilà, thanks Ray.

 

Sadly, we are both still stumped on the two character middle section. 

The second character appears to be "ha", but I am not sure of that and neither of us know what the top character is, or how the two are read.

 

Which brings me to why I write.  Can someone please enlighten me on these two seemingly simple characters. (middle section).

 

Thank you,

Ed

Damn, I knew someone would come along and just like that solve my question in the blink of the eye.

Thanks Guido
