I have seen several pictures of British L1A1s that appear to have been rebuilt for war reserve before being sold off in Europe, and a number of TMH assemblies in America that look to have been rebuilt at least once in the past. However, among these I can only recall seeing one example (a TMH in America) that appeared to have FTR markings.
Was there a marking protocol for FTR or base workshop rebuilt L1A1s in British service?
