37mm Projectile ID needed

[hicky1300]

Hi All
Had this in my collection for years.
Fairly sure this is not the correct projectile for the case??!!
No markings.
Looks to me like a 37mm APBC projectile & I think is it Russian.
Anyone clarify for me please?

It kind of looks like a Russian Aircraft projo, but your photo is so small it is hard to tell.
