Some of the Monogram molds are holding up just fine. I have an old Goshawk and the new one from Starfighter,,,,there is no difference in the quality of those two shots, so I would say that 1970's mold is okay today. Has anyone noticed any difference in the multiple Monogram releases, the Hasegawa releases or the Accurate Miniatures releases of the 1/72 Phantom. Granted, there are two sets of toolings sharing the work load, but, that kit has been released and re-released for decades now.
Since I want some of the ancient Monograms when I go to the shows, the only one I could buy today was the F4B-4 from a dealer, he bought it at the show and then sold it to me when I asked if he had seen any this morning.
The old kits I mostly see are Airfix, Testors, and Hasegawa at the shows I go to,,,,,I think folks have snapped up all the Revell early boxes for kit collections. Some of the more desirable Monograms went that way as well, I think.
out of all the vendors I saw today, I only brought 5 kits home with me, one old White Box Monogram, one old Airfix-72, one old Hasegawa Armor, one new Hobbyboss Panther, and the new Airfix Airborne Jeep.
Today's tables were about equally split between new kit/new supplies vendors and "stash disposers".
ps Hasegawa Hornets are practically stocking stuffers this year, some I saw are cheaper than Hobbycraft 1/72 "anythings"
