I am looking to build this particular St. Chamond Tank. My question is with the muffler on this tank. Is it missing its muffler and the exhaust pipes were left sticking up or is this a specific modification? From the picture the exhaust pipe extension is still intact and looks that is was just reconnected to the rear exhaust pipe.
From what I can find, it looks like the muffler was removed for some reason. According to the "Char Francais" website - www.chars-francais.net/2015/index.php - all models of this tank originally came with a muffler.
It's a shame you can't read the numbers better to find out exactly which tank it is.
