Mike ;

these are actually fairly easy to repair and salvage , it just takes patience and time .

You need a spare one to brake up into bits and Acetone (I *think*) to mix up and make a thick paste you them use to both glue the cracks and hand fashion the missing partsĀ  , then allow to dry , sand , paint and you're good to go .

I have one so repaired by a guy who used to be in another CT90/110 Club I'm in , it looks fine 10 years later .

Because it's junk now , no reason why not to experiment with learning if you're game .

I don't know what typ of plastic it is but once you find that out , googling " repair XXX plastic " will fill in the chemicals needed and cautions about proper handling so you don't get any chemical burns nor set the garage/house afire .
