Help identifying knife

[Bthomas855]

Hello All,
I am hoping that someone can help me identify this knife. I bought this knife from a gentleman that said he got it about 30 years ago and can’t remember the maker. The blade length is 240mm and is a deba.

Do you know what the steel type is?

If there was a stamp for the steel it would be on the back side or on the tang
