Thanks Jack...I don't like the grip it came with, because it actually blocks one of the rounds from coming out, and so I have to turn the carousel to get the round out.

I have the box, and there's a sticker on the box that says the following:

S/N: AEU8285
Model No: 60
Barrel: 3
Fin: S
Stock: SB

Does that help? Unfortunately, there's some torn-off paper covering the Product Code.
