That is a great accessory build. Thank you for all of the detailed pictures.
I have always wanted to do something similar for parades. I was going to with card board tubes, epoxy and a baby seat to the side of the blast shield. That way way we could throw a helmet on my buddies toddler, strap him in and give the crowd something to ponder.
Again, it is a great build. What did you use as reference for your build. Were you part of the artillery in the service?
