M4A3 Sherman "Calliope"
I have built a Dragon Wagon and thought that it could tug a tank. I found a M4 Calliope from Esci on my shelf. This model is old but I had M4A3E2 from Extra Tech (one of the biggest mistake of this model is wrong tracks without duckbills so I am waiting for new model by Dragon). Turret and launcher are from Esci, the hull and chassis from Extra Tech. I have added some details to the launcher (it was very simple) and a lot of equipment. The carton boxes have been made on my printer.
