yep, along with some money...
It just kinda bugs me that Cox would stoop so low to buy/lease/rent a mold from Testors!
This isn't the only time something like this had happened, after Comet went under the Tri Pacer ended up with Aurora powered by the Stallion .049 and their Se5a D-7, p-40 & p-51 as screw together plastic kits.
Its possible and was common to modify the mold of these planes over the years. Some of the Comet models went thru two, three, four different engine configurations.
Here's one example, the Comet Regulas was latter re-introduced as a 'T38' with a cockpit added and the 'new' .059 Cub reedie with push button spring starter!

Depends on the mold. Some injection forming molds have hundreds of pieces that fit together, including cavity sections, springs, sprues, ejectors, etc. This high of a number is more of an exception though.
In some cases the large number of pieces is to allow for less complex and more accurate machining of the mold cavities. In other cases it is to allow version changes without replacing the entire assembly, but breaking it down and replacing a part (this is a BIG job all the same)

Wish it flew as good as it looks... I've still got the orig. red spinner and prop... was either a 5-2 or 5-4... but I have them both (with the spinner bracket on the props' hub) If it was designed (by Cox...) more to the size of the PT-19, it might have flown better. I'd love to build a built-up balsa version, maybe 22-24"/110-120 sq. and more elevator area.

Brodak offers a profile balsa version with a built up wing if you wanted to save some time.
