Help to identify Spanish CW bombshell

[blau250]

May someone help me to identify it? Picked today at a local flea market. The seller told me that it is from the Spanish Civil War, and really it seems very old.
It is impossible to assemble/disassemble it. Seems to be empty but it is not a lightweight piece.
Many thanks ni advance....

If you don't have any other information, dimensions are most important. Diameter of the case and shell, length etc.

I think, it is 37 x 95R for Hotchkiss cannon.

Or for Puteaux cannons

Some pics with measurements. 17 centimeters long and 4 centimeters diameter.

No round I could find. I guess you didn't get the dimensions well. Basic dimensions are:

Diameter of the shell
Length of the case.

Have a look at: http://municion.org/

it could be the 37mm Hotchkiss round as klarkon mentions, as it's total length is 16,6 cm and shell diameter is 3,7 cm.

Cańón Puteaux de 37 mm, modelo 1916, de origen Francés.
Cańón Puteaux de 37 mm. de carro de combate Renault adaptado para acompańamiento de Infantería. (Rectificado por Artemio Mortera, ponía originalmente Cańón contracarro 37 mm Renault.) Se trata, según nos informa el Sr. Mortera, de un apańo artesanal y que originalmente era el arma que montaban los Renault FT-17, y que en ningún caso tenían capacidad contra-carro. Empleaba el cartucho 37x95R.
