james-l beat me to the serial number identification. The side of the action should have bolsters on it and the number of visible screws differentiates The Crass from the Minier and Lewis.
Here's a pic of a Minier I have for reference:
Actually I am unable to remember right now whether my gun is a Lewis or a Minier???
The serial number listing on our "other useful information" section shows my gun to be a 1902 Crass. However due to the four screw frame, I think its either a Minier or Lewis model.
