820A Cab w 808 multicell.

Thanks for the pix! This could not have been easy to cast, but faster than soldering up all those cells by hand.
Maybe something like this could be cast in an inert resin.

During the WWII aluminum shortage and right after they were urethane foam.

So far he's made $4700US for the H808 and the 803As.
Those urethane foam ones are the really rare and expensive ones, mind you the metal ones are prob even rarer but survive better.
