laurieb,
I can't help you but I just wanted to say that your question is one of the things I love about PPRuNe. Someone asking an arcane question about an 80 year-old aircraft with every expectation that someone will be able to answer it.
I'm on the same wavelength as someone who used to be able to state the significant differences between every mark of Spitfire and all the diffent versions of the Avro 504.
