Finding someone who has these "gun sights" and is willing to part with one is very improvable. The Modelhause made resin copies but, their no longer taking orders. All this being said, I needed a pair for my 60 Mercury glue bomb. As a result, I took the pair from my 59 Ford "retractable top" kit and resin cast them. I can send you one if you wish. Your 100 miles from me so hand delivery is out of the question.
As far as any kit manufacturers issuing any new 50's kits, I can't see it. When Modelhaus was in business,at least you could get a resin copy of a desired year car. Even at that, it is far from a kit. Here is my list of model kits I would like to build. How many do you think would be even be considered to garner enough demand to manufacture? 1955-56 Plymouth 1955-56 Pontiac 1955-56-57-58 Dodge 1956-57-59 Olds 1957-58-59 Chrysler New Yorker 1957-58-59 DeSoto Fire Flite This is not a wish list. It's my to do list. All will have a rolling detailed chassis, Engine bays complete with correct engine and detailed interior. It has been my opinion for a number of years that, the only way to get a model kit of a subject you want to build, is to create it yourself. In order to do this, you need to have certain skills.
Well, all went well except I have no power. The storm did a god job of trimming up the branches of my trees. Nothing now but boredom as everything I want to do tacks power. I don't care for this cell phne version.
