Since it's in hanover, it's probably the same Tiger they show from time to time at Reading. I saw that one from
about 5 foot away. If it has a chuck out of one of the roadwheels on the right side and the turret hatch is decorative
plaster/concrete/zimmerit it's probably the same tank.
For the record here. It is much closer to Dillsburg than Hanover. It may be the same one at WWII weekend though, I really wouldn't know since They were not open for me to ask.
I really didn't take that close of a look to see if it was real or not. My untrained eye would not have ever caught the differences in it.
Personally I don't care if it is real or not, I thought it pretty cool to see it sitting along the highway that I had to stop and take a pic and share with all. This thing still took a great deal of time to make this way and since (according to Guppy) there are no real specimens in the US then this is probably going to be as close as I can get.
No matter what it was a nice to see and I will still likely stop and see if I can get a closer look if time ever permits.
