Title: Mk1A Guns
Post by: baldeagle on January 15, 2010, 11:28:46 PM
I wonder if anyone can explain why some drawings and even photographs show one or two of the guns protruding forward from the wing of the Spitfire Mk1A. Other drawings show no gun and many photographs show the ports taped over which would clearly be impossible if the guns protruded. Please help...

Initially the guns carried flash eliminators, some of which protruded; according to armourer Fred Roberts, in "Duxford to Karachi," they were removed at the outbreak of war.  At first, there were "covers," for the muzzle tubes and ejection ports, but they were replaced by the fabric patches during 1940.  I haven't been able to find out, yet, what those covers looked like, but, from drawings, it looks as if they slid inside the muzzle tubes, inside which there was a slight step, to accomodate them.  The Spitfire modification, for the patches, was introduced in late September, 1940, but it's entirely possible that the Squadrons began using them earlier, and Supermarine were just catching up, with a new design of blast tube, etc.
