Translation assistance with sayagaki

[TenguSan]

Hello,

 

I recently purchased a katana with a shirasaya which has a sayagaki from Honami Koson. I got that much from the kao and some other similar posts here, but am not having much luck otherwise. 
Any assistance is appreciated.

 

best regards and thanks in advance

Hi John,

 

Here's my best guess:

 

兼信 = Kanenobu  [I'm not 100% certain on the reading of the first character]

 

長貳尺貳寸六分 = Length: 2 shaku 2 sun 6 bu (~68.48 cm)

 

昭和癸巳卯月 = April of Shōwa, year of the water snake (Shōwa 30 = 1955 CE) (Shōwa 28 = 1953 CE)

 

本阿弥光遜 [花押] = Hon‘ami Kōson [kaō]

Thank you Moriyama san. Indeed, 癸巳 is the 28th year of the Shōwa era (I got confused since it's the 30th year of the 60-year cycle).

A minor correction,

Shōwa 28 = 1953

Thank you very much Xiayang and Koichi! It has papers with NTHK attributing it to early Edo, although the seller was certain that Honami Koson was right that it is late muromachi.
