I've been a customer for 45 years and have purchased many varied pieces over the years. After a few cannons I decided to buy the Coehorn mortar. While the casting is even more crude than the originals and the trunnions aren't quite round I am still satisfied. The much smaller bore and the welded steel liner makes it both safer and less expensive to fire. The carriage is just a box so it was easy to fabricate. You'll be the life of the party on New Years and Independence Day!
