so what is the scale of the CR90 did we ever find out?

I'll measure it up again when I get home, but IIRC it's very close to 1/460 at 320mm long. It *just* fits in an IKEA DETOLF cabinet facing the door.

Edit: Unless you take an actual LFL digital model as the source, any determination of scale will be flawed. These are make believe ships and expecting to be able to calculate a consistent scale from their depictions (even sets vary the size inconsistently) will lead to madness and flame-baiting. Model casual.

I took my drafting ruler to it and got 333 millimeters, which gives me a 1/450 scale.
