Trying to get a new canopy sprue for my 1/32 Tumpeter Wildcat. Having no luck at all.[cnsod]
This is a long shot but it worked for me recently. There are sellers on ebay that will part out kits and sell the kit one parts tree at a time. I had a Ju-88 kit where I screwed up the canopy.
I went on ebay and created a search that would email me whenever there was a hit. It took a couple month but a seller finally showed up selling the clear parts I needed. I got it for $8 shipped.
You could always try this strategy and shelve the build for now until the part shows up.
Also as mentioned you could cast a new part from the one you have. Fix the one you have and sand the crack as smooth as possible. Create a mold using RTV silicone with the repaired canopy. Cast a new canopy using clear resin. Alumilite sells the RTV and clear resin at most craft stores or buy it online. You will have enough RTV and resin to mold and cast lots of parts.
I have a 1/72 scale canopy set for a two seat a-7 hobbyboss. My email is benzay@comcast.net
