Here's my A-4, built around two decades ago.
The in-scale Tiger was built by a friend and was thrown in for size comparison. The A-4 was a large rocket, but could not compare to the ones built following the war. I had a photo of a 1/144 A-4 next to an Airfix Saturn V, and it looked like a toothpick! Sorry, I did a quick search, but the photo is on a external drive somewhere.
The white metal stand required lots of cleanup, as you know. But it is pretty sturdy - and heavy!
Looking forward to seeing yours finished in camo colors.
