[Fot] MYSTERY CALIPERS-HELP!

[N197TR4 at cs.com]

List:

I have a pair of calipers adapted to "race car since new" TR250. (I have no 
personal history with this car)

It is a THREE POT CALIPER bolted to the existing the caliper bracket.

The caliper wraps itself around VENTILATED ROTORS with a five position bolt 
circle modified to four position....same bolt circle diameter.  (Jaguar?)

....anyone familiar with this?

We are evaluating this set up for use on a Listers Vintage Racer  (TR3)
