Those look good, thanks for the post/pictures!

Are all of the nuts/bolts on the front armor (zusatzpanzer?) "real"? By the looks of it, I'm guessing they are all real bolts/nuts.

Sometimes pictures are deceptive, how do YOU think those nuts/bolts compare to photos of the real thing? IMO those are definitely "close enough" to the real deal, whether dead-on accurate or not.

Scaling up the nuts, that would be 48MM, and sounds/looks to be a reasonable size.

Did you get them anywhere specific? The nuts look thinner (not as tall) as the ones I've been able to find online.
