I need a bit of help identifying this caliper and upright from a '70 Rostron FF that I'm restoring. I'm told that the upright may be Lotus 19 but the caliper mounting holes are 2.125" spacing, which doesn't match the type of calipers I'd expect on a Lotus 19. The caliper (top right) is similar to an LF-14 (shown below for comparison), but also has the 2.125" mounting bolt spacing, a ~1.325 diameter piston and the brake pad is a very strange shape. Otherwise it's pretty similar to the LF-14, so I think it's a Girling. At this point I'm thinking I'll convert to LD-19 but that requires a lot of whittling. Any info or suggestion is appreciated.
