You can still get the plans for the Bulldog from Cleveland Model supply. Youd just either need to scratch build it. Or find a cutter who can supply the kit in the scale you order the plans. Due to the fact that the written dimensions on the plans would be wrong its more difficult i believe. Reason for that is because Cleveland Model plans are blown up from i believe 1/16? so the plans may state you need a 1/8 stringer but in fact the scale your building needs much bigger.
Hope i explained that understandably.
