Nice try Alastair but you're probably going to need BSF I'm afraid! :-D
Not sure about the engines though, I suppose they could have been ANF and ANC due to their origins. UNF did not exist during the war, the sizes only becoming 'unified' in the 1950s I think.
In general, the standard ANF and ANC pitches were adopted as the unified sizes but not all. As an example, the favoured ANF for 1" was 14 tpi, unified settling for 12 tpi. That can cause problems as there is a lot of 1" in Shermans.....
