Just to complicate things still further, I believe most of the Signals Command Varsities actually had yellow cheatlines oulined in black, but with the usual dayglow trim on the rest of the airframe (as seen on the colour shot on the last page in fact). From what I've seen, I think it was mostly Topcliffe that had Varsities with the afore-mentioned dayglow/zigzag cheatline, but I presume other units had some too. It just seems odd that the only Varsities I can remember seeing at Strubby had the zigzag dayglow cheatline and yet all the CAW Varsity photographs I've seen show the straight blue cheatline. Strange business indeed!
