You are a little late with that one.
I hear we have loss Williams Bros due to the virus and a supplier shortage. Even their website has disappeared and no one seems to have much left of their products in stock. I don't remember the website but another supplier had a banner saying orders were no longer being accepted and they were temporary closing until products become available. I have stopped looking at kits on Ebay the flippers are driving the prices too high I will stick with plans and having short kits cut. The end cost of the completed model is less than a lot of these kits for sale.
