Dutchman - Benecia Arsenal is located near the town of Vallejo, California, somewhat northeast of San Francisco, and across the bay from that city. It is most famous around here for the Camel Barn, which is now a museum. Benecia housed some of the Camels that were used experimentally by the U.S. Army in the late 19th Century. Some don’t know that the U.S. ever had a Camel Corps, so to speak.
Today it is primarily like a park. I honestly don’t know if there is any purely military activity there anymore. It has been years since I visited the old post, and of course, our first stop was the famous Camel Barn!
On a personal note, when I purchased a M1911 .45 Pistol some fifty years ago thru the DCM, and saw from my invoice that it was being shipped out of Benecia, I went up there to pick it up hoping I could pick one out. Well, all I got was scolded by a tough old Sergeant who pointed out that the Invoice specially said to wait for shipment and not to go to the shipping point to pick it up. He gave me one anyone, and completed the paper work, but when I asked if I could pick one out, he (rightfully) laughed in my face, when in back, brought out a sealed box and gave it to me. I will never forget the last thing he said. “Open it for Christmas and be surprised.” Unfortunately, when I got home and opened it is was a WWII (or after) Augusta Arsenal rebuilt, mixed part M1911. However, it was in rebuilt new condition, and a perfectly serviceable .45, the first of many that I would own in my life.
I think I have a book I bought at the Arsenal Museum. If you have any specific questions, I will try to find an answer in there, although as I recall it was long on general history and short on any specific details about ammo production and repacking there.
The Pueblo box is great! I never saw one before. My Dad was a railroad station agent there, I think during WWI, and met my Mom there, who was teaching school in Pueblo. Don’t know if there was an arsenal there then, or not. They were married in 1918, so it may have been before the military facility was built. I know little or nothing about it.
