Malta Roundels ?

[Malta]

This is a two page section of a notebook of a fitter who was on Malta Sept 1941 - December 1943, attached to 249 Sq. Could these be notes about roundels?

They appear to be dealing with distinct panels.  My initial thoughts were for thicknesses or clearances, but I gave up on that.  I think the 2C, 1C, 2B etc references have to be the key, and could suggest that they apply to different fasteners?  Note that one of the descriptions ends with the word "screws".

 

If you don't get any good response here, the Flypast Historic Forum has a lot of posters dealing with the restoration of WW2 aircraft, so someone there may well be able to help.  Come to think of it, they are likely to be very interested in your fitter's notes anyway.  http://forum.keypublishing.com/forumdisplay.php?4-Historic-Aviation
