Help With Serial Number Please!

[Bruce Pennington]

Katakana "I", but the numbers aren't very clear. Anyone make out the numbers on this Mantetsu nakago mune?

[Stephen]

Last is roku i was thinking 326?

[ROKUJURO]

Probably easier with a good photo....

Might help not to magnify it quite so much.  I agree with Stephen, but don't know why the first two strokes of the 3 are so much lighter than the rest.

[Bruce Pennington]

Thanks guys! It came from AoiJapan sales site. Here's the full-sized picture. It's not high-res enough.

 

Sometimes someone is able to recognize the kanji hidden in the mess, so it was worth a try. Thanks Stephen! Your guess is along the lines I was leaning, so I'll go with 326.

Bruce,

 

I think this is a case where taking the zoom lower than higher is best.  When I set the zoom to 50% and look at it with a magnifying glass.

I believe I'm seeing 314.

[Bruce Pennington]

Aoi Japan graciously sent me the original picture and I can see the number more clearly. It is 336!

五二六

 

I'm willing to entertain 五三六, but to me it looks like 五二六.

[Stephen]

With the small enter strokes i agree with Steve. Still blur to my eyes.

[Bruce Pennington]

Yes, I see the 5 clearly now! The second kanji could even be another 5.

[dwmc]

That second kanji does look like it could also be a five. But as Stephen mentioned, still somewhat of a blur.
