PeterA, I have a question: I found this old thread.
http://forum.12oclockhigh.net/showthread.php?t=15415
here somebody requested almost the same info from a CBAF Spit dataplate.
You explained then that
"drawing number 30027 SHT7 Issue 14 is in fact the firewall and because of the CBAF construction number will be a Mk II. Issue 14 for this drawing is dated 10 July 1940 incorporating Modification number 76 which was Mk II specific."
Since my plate carries the same marking 30027 SHT7
Issue 14 should we then deduce that my plane was a MkII as the CBAF example? Or being a 6S Supermarine product the Issue 14 does not apply and is then a MkI?
Thanks for the explanation.
I checked the X435X range, but no real candidates. Only X4342 would fit but was a (converted) MkV...
Thanks for your help.
