The 105 is a beautiful aircraft - and an absolute monster. I worked on the 105 and I especially recall spending most of the night to repair the auxiliary fuel tank pressure regulators that were flown in by F-4's baggage pod to the Wild Weasel unit at George AFB could deploy to Europe. After losing an F-105F at Savannah we found that the aux fuel tank regulators on the entire fleet were potentially ready to blow at any time. There was a built-in backup regulator in the units but some AFLC genius had decided to stop doing time compliance change-out, and when you blow air through something for years without it having to function, the back-up regulator is likely to freeze and feed 150 PSI rather than 11 psi to the tanks. I personally concluded that type of failure likely did not cause the Savannah failure but we still had to fix the regulators. Without its bomb bay, belly, or wing drop tanks a F-105 has a nominal endurance of 0.5 hours. It is tough to get from CA to Europe in half hour hops.
Then I had to run up to McConnell AFB to get the Reserve unit's 105's up and running. They did all the training and thus had a busy schedule. We ended up having to remove the regulator from a crashed 105 they had in the junkyard and use parts off of that, but I got them all back in the air.
Good luck with the model. I have a Monogram 1/48D and a G myself.
By the way, the airplane depicted on the box top is now in a museum - in Poland!
