Here is a very rare part. We know a few things about jags, but this one had us stumped for some time. We purchased this with a lot of Jaguar, Mercedes, Triumph, MG parts etc. We called everyone, even jaguar, and no one knew much about it. Just recently we were able to have some level of confirmation. We have pictures of a C Type with the XK1041 casting number.The numbers stamped/cast on the gearbox housing are XK1041, WM4847 and 2200B.
Please ask any and all questions or if you have better information on this, please share. We are very curious to get to a conclusive understanding of this part!
