I quote:
“….. poor quality image that purports to be of SX273, the codes are arranged S5*0 in the port side. If there’s a better image out there of that aircraft from the p/s, be great to have it. ”

Also, SX277 was coded S5-M on the port side .

Not there is a typo, the squadron should be 741 not 714

My original post mentioned S5-M as pictured in the Crowwood book.

The Airfix kit I bought had a note enclosed correcting the Squadron number from 714 to 741.

I think the Warpaint book also gives a different Squadron number altogether for both aircraft. I don’t have my copy handy, so can’t confirm.
