lost canopy

try this, write Marco Polo Distributors(they import the Hasegawa kits into the US) and give them the part #'s and kit#'s and they should send you the missing parts for free, I know Revell/Monogram have a site that does this but not sure about Hasegawa, it wont hurt to try

from what I have seen in the past , hasegawa and tamiya parts are easy to get ,but only if you live in the US.
Here in Europe , it is a different matter.
You have to contact individual importers and waste your time waiting for them to not contact you.

Tamiya/Hasegawa 0

You would probably have more luck buying an aftermarket canopy.
