Hand cannon?

[Doclane]

This is been handed down for generations and the interpretation of what it says has been lost. Can anyone help?

So it says OTTOMH in Chinese is That  the maker or word meaning something? thanks DocLane

Off the top of my head it says, …can you get even more clearer shots of the writing?

 

Although it appears to be an ancient Chinese hand gonne, it looks to me as if someone has added rather clumsy pre-WW2 Japanese Kanji and Katakana script to it, for whatever reason.

 

Potentially an interesting object!

Hope these will help. There are two seams one on both sides.

[Bugyotsuji]

If legit, 1300s? See Huochong.

Had a XRF test done 64.24% copper and 35.76 zinc does any one know the percentage of the metals for a huochong?

[Bugyotsuji]

砲金 Hōkin gunmetal was around 90% copper and 10% tin. Little to no zinc, I believe. (Not sure when zinc first came into use…)

 

Quote: Two bronze cannon, cast in 1535 and 1628 respectively, were recently recovered from the wreck of an old Swedish warship, and were found to be only slightly corroded. The alloys used for these guns contained 84 per cent and 14 per cent of copper respectively with up to 14 per cent of tin and a little lead.

copper and zinc was used in the Ming dynasty for there coinage. Do i need to have more testing done on the Huochong like maybe carbon dating the Huochong?
