Antelope / Gazelle

Can anyone help in explaining the difference between a Wassell Antelope and a Wassell Gazelle please. Was one a trials version and the other motocross?

Tyran Photos

With the help of the search facility at the Penton Owners Group site I have come across some pretty good photos of a Tyran at the Clarionconst website. The Tyran is the equivalent American verion of the Wassell Antelope sold here in the UK.

Lots of Work

Plenty to do without even starting on the engine!

Engine and Frame No.

Can anyone tell me if you can age a Wassell from its frame number. I know from the POG site that all Penton models can be aged this way but the frame number I have isn't in the same format.

The frame number is W2722MX and Sachs engine number 7317465 which is a 125/6b.
