Wow! I've been wanting a carriage like this for ages. This one is laser-cut from heavy chipboard. It ships flat but a breeze to put together with the slots and tabs precut (you'll just need to secure with a bit of white glue). And comes complete with the wheels and dowels for axles.
Finished size is 9-3/4" long (including the wheels) x 4" wide x 5-1/2" tall (and can accommodate a 6" long coffin).
This item is in Dollhouse 1:12 Scale
