Maybe. The boat is 1/25. Airfix made a 1/24 P-51D Mustang with a Merlin engine. This assumes that the stated scale for each is correct. Their old Spitfire may have had a Merlin, also. I believe their new(ish) Spitfire has a Merlin, too. Hmmm I wonder about their 1/24 Mosquito from about ten years ago??
