John,
I went though 40 or so just now, and ALL of them have the
relief as pictured.
Casting numbers as follows: LH caliper indirect half (outer
w/o hose connection) 3243-220 Direct 3243-222
RH indirect 3243-331 direct 3243-223
I've never seen a caliper without it. If you go to an old
BMC parts catalog, there was a supercession at the beginning of disc
brake applications. Perhaps that was the difference. It would
probably be harder to find those early ones than not.
