My grandfather Loran and I saw this American Locomotive M7B1 Priest at the Yuma Proving Grounds in 2000. The road trip back from Quartzite, Arizona, in the spring of 2000 was the last time I saw him before he passed away a few weeks later. Closer to home, the Flying Heritage Collection has added a Priest to its impressive gallery. Others I have seen during trips to Wyoming and Mississippi.
The Priest replaced the T19 105mm HMC (Howitzer Motor Carriage) Half Track
