Inside a Mark IV Male
Looking through the tank from the right to the left midsection. It was very dark, hot, cramped and smelly inside these tanks and the ride was not as comfortable as nowadays. See picture #1904
The Mark IV was built by six different manufacturers: Metropolitan, Fosters, Armstrong-Whitworth, Coventry Ordnance Works, Wm Beardmore & Co. and Mirrlees, Watson & Co.
