200x cam identification .

[bandito90]

In the process of rebuilding my 200x. I got a cam out of an XR200 motor. The cam is bigger and definitely not stock.
It's engraved with : WB 101.3 9.02

Just wondering if anyone would know what cam this might be? Is it possibly a White Brothers?

Thanks

Could be a web cam, don't quote me though
