There's an m8 over at the american heritage museum in Hudson MA. I think there's a marine landing craft that has the same turrent. Not sure if you're anywhere near that.

Can't say enough about the quality of their exhibits. All the armor you've dreamed of, in running condition.
I've only gotten there once, but i'm itching to go again.
Do you know if they ever found the breach block to the Flak 88? I was last there in 2018 and they had sold one of the Spanish post war 88s (they had 2, sold the one they blew up with an overcharged blank years ago) & bought a real wartime German one. Then they promptly lost the breach block from one. I forget exactly which but it came up when the other Spanish 88 was to be used for their reenactment.
A lot of their stuff came from the Littlefield Collection. Which is great they can be stewards of history and continue to preserve these vehicles. Jacques Littlefield & Bob Collings have always been in a world most will never attain due to their wealth. My big problem was Bob had the balls to ask the reenactors to donate gear & equipment to his museum for the vignettes. That was a hard no, we’d just wasted days off work to spend money to be there all to play in his staged farb-fest in exchange for a bag of the cheapest blanks and some pink sheet cake. It was different when he pulled out original vehicles for the event. Now it’s just replicas that reenactors bring since everything cool is a permanent exhibit.
If I sound spiteful, it’s because of the injuries. I got injured in my eye because of poor safety on the part of their pyrotechnician. A friend almost lost his eye there for the same reasons just much worse. Not to mention the blown up 88 breaking a guys arm. It’s not a Collings event without someone going to the hospital. And Bob ignoring it. His “battle for the airfield” is a safety nightmare.
