Welcome, Merle!
Yes, that's a Venezuelan FN-49.
The tiny little white tag above the magazine says 7mm, so I don't confuse it with my 8mm Egyptian.
I thought I saw a muzzle break there.
I have one too, but it came without a mag.
I ended up modding a repro 8mm mag, and it seems to work OK.
I'll find out pretty soon...
