With reference to “Performance Uprating” (Motor Sport, March 1988), I have three comments.
First, your photo is captioned as “The MG factory in 1935”. It isn’t— there are too many out-of-date axles lying around.
Second, you said 17 J4s were built. No, there were only eight, or possibly a ninth unfinished.
Third, you said “Current owner Karl Weissman has rebuilt the J4 to a high standard”. Nonsense! The late Geoff Coles did all that work, and probably set a new standard for all MG rebuilds. As a matter of fact, he won the Spero Trophy a couple of times.
