Re: Question on my 1937 Twelve's Engine Number

So my thought is the early 1937 Twelves had the A suffix and then it changed to ???

I don't think that holds water. Here's a list of 1937 Twelve engine numbers known to me from my theft-proof data collection study. They are in order of lowest to highest theft-proof numbers - so more-or-less in the body build order. There are earlier engine numbers without the suffix. Though pretty slim amount of data to base conclusions on, no apparent correlation to chassis type either as both these "A" engines are 1507s, as are both earlier and later motor numbers without the "A". Both of the "A" numbers were on body type 1036 but so was 905539 if that means anything. It remains a mystery to me, at least for the moment. I've asked one of the major rebuilders of Twelves if he knows - and await a response.
