Are these two US grenades original?

[Anders]

The Lemon type is marked RFX55 M12 and the fuze M228.

The Baseball type has no markings at all and the fuze is also an M228.
Several things regarding this grenade raise a red flag. First of all it is unpainted and there are no stamps or other markings to identify this grenade. Second it has a very crude finish even for a practice grenade.

What do you guys think are these grenades original practice grenades and also is the fuze M228 the correct model for these types of grenades?

Hi. Both of the bodies are reproductions. The fuzes are from M69 practice grenades. Cheers
