Thank you Ruairidh, I am sure Tim is very well versed in Late Ruby and Big seven matters, his article come across as such. As owner quite a lot of big seven stuff, and of A/RR Ruby chassis number 286999 I am also pretty well versed in such matters so was providing some further insight. I do not however profess to have any real expertise with Big seven engines as they have never really interested me in any way.
