It's a shame there's only ever been one styrene CSM released in 1/48, and that's the one on your workbench. That one has
always been something of a rare bird too. I don't know if it was the awkward size of the box, the cost, or both but it was never an easy find.
Understandably, the LM kitted in several scales (Monogram, Revell, Aoshima - 1/48, Airfix - 1/72, Revell, Revell AG, Aoshima, Heller - 1/96, Monogram, Airfix, Revell - 1/144, and Airfix, AMT - 1/288), but to display both vehicles in scale, you basically had Revell, Revell AG and Heller at 1/96.
Yeah, I know both spacecraft were done in 1/144 & 1/288 as part of the Saturn V and Saturn IB (talk about an inaccuracy!) but at those scales, detail is far too simplified.
It'd be great to have a readily available, accurate CSM in a standard aircraft modeling scale like 1/48 since we have the LM, Mercury and Gemini at that scale (though the Revell Mercury and Gemini are getting scarce too. Not counting sleaze-bay, last I saw of them was the Grissom comemmorative set...10 - 15 years ago).
Since none of the maufacturers saw fit to correct the inaccuracies of these kits in the last 40+ years, I seriously doubt we'll ever see new tools for any of them in styrene

.
That's where realspacemodels came in. Excellent, accurate kits of these spacecraft in
several uniform scales. Only real drawback is trying to do "in flight" displays due to the weight of the solid resin.
BTW: beware the Revell AG Columbia & Eagle kit...detail is VERY soft and the plastic is too.
