Admin,
Here's a wee bit to unscramble.
Original RCAF number is 21157. No photos there; can be deleted with the links.
N155X I'm thinking wasn't FAA generated, so if the c/n is changed to the same c/n as N133AT and make the type the same as the FAA generated N133AT, they should link nicely. A note can be made as to the actual c/n vs. the FAA's use of RCAF s/n
