I've been in contact with MWS for several years off and on now and Isabella has been a great help with my questions etc.

They have both 18" and 19" 2.5" wide rims in both center and outer lacing configurations.
They use the MG TA wheel configuration for the M3W. I'm sure that this spoke hub will fit many other British cars, but they do list it for the MG TA and Morgan Three Wheeler on their web site.
If you go to their website for their catalog files. In that you can custom fit about any hub to about any wheel. They can also go up from the 48 spoke now to a 60 or even 72 if needed.
Some of the rims and combos are limited and chrome/stainless may not be available in all combos. Actually the cost is not all that bad.
A friend of mine ordered the MG TB/TC wheels from Moss Motors that were in chrome and have the center lace pattern. He paid over $500/ea. I think MWS would be cheaper even with the shipping etc.
