Considering the price of a
FW Earthshaker battery, I'm looking at historical miniatures as a stand in. I'm struggling to find a good size comparison, but it seems the best fit would be a 1:35 or 1:48 flak 88.
I've also found this:

Does anyone know the relative size of this model? A picture of it, or any other appropriate model, next to a 28mm infantry or just a scale would be greatly appreciated, thank you.
