If I've ever been in this position, my instinct is to look for the online catalogues of real world equipment suppliers, who (helpfully) tend to dimension their products. However, in this case (pun unavoidable) it was less useful: Beta Tools' cabinets seem to mostly be around 800mm x 400mm footprint, which seem a fair bit smaller than yours. For what it's worth, by my eye I think the larger one looks more to scale - even before you've added the 4" vice. That said, I think it's clear that you and Peter have better eyes and fingers than the rest of us mortals. 😉
