I can add two issues to Don A.'s list of MRNs:
After 1983 #1(Spr) #2(Winter)......

A catalog size MRN with no date other than 1983 was printed. No volume # either.
Main article was the Launch of Columbia, and the design plan was Skylark.

Then Vol.24#1 came in the Winter 84 Estes Catalog.
It also was a catalog size MRN, the main article being Spacelab, and the design plan was Pee-Wee.

Then back to Don A.'s list 1984 Spring Fall Winter
