Made from scrap wood. Sizes for each entire unit is about 30 inches long, 6-1/2 wide and 7 tall. These are toys, not intended to be models. Built sturdy enough that they should stand years of play. Also generic -- no brands implied either.
Cut with scrollsaw . Used a lot of other tools too. Pattern by T. & E. designs as many of the ones I use are.
Fun to make. Blue one is for a great grandson that likes to be with me in the shop.
