I don't have time to look if I have somewhere Hopp's docu but here is something else, IMHO better than the early 1940 figure because Supermarine Woolston was fairly small aeroplane factory which before Spitfire mostly produced flying boats. Castle Bromwich, which began produce Spit Mk IIs circa September 1940 was a mass production factory which is shown in man-power figures. One point to remember, Supermarine was more flexible plant and it produced e.g. Mk VIIIs and XIVs, which had retactable tailwheels and also smallish fuel tanks in the wings besides the fuselage tanks. So while CB spitted out IIs, Vs , IXs and XVI, Supermarine also produced a bit more complicated versions. So I'm not quite sure on the logic of Hop in that Supermarine could produce Mk VIII less than 13,000 hours in 1944 because it had used 13,000 hours for Mk Vc in 1942, entirely possible but not sure.

Spitfire V ME109. I have found these links on the net.

All figures from Sebastian Ritchie:
1942, Supermarine man hours for Spitfire Vc: 13,000
1941, Castle Bromwich man hours for Spitfire (V, presumably): 10,400
1944, Castle Bromwich man hours for a Spitfire: half the hours Supermarine required in 1944.
Given that man hours reduced throughout the war, Supermarine should have required a lot less than 13,000 man hours, and Castle Bromwich would therefore require less than 6,500...
