You seemed to have missed the sarcasm in my post there 81C.
*I* model pre-WWII and am fed up with top feeds being obligatory for the last 35+ years on GW liveried locos. Given how the manufacturers are now able to model variations on a theme e.g. Hornby with the 2800, 8 coupled tanks and Stars being available with variations of straight/curved footplates, with/without steam pipes etc, then producing models with no top-feed option to match the livery and timezone they are supposed to portray shouldn't be beyond them.
And yes, to those who might want to say it, I have "done some modelling" and removed top feeds off an Airfix 14xx I bought for £15 30+ years ago and one of those surplus 57xx bodies that were on eBay a while ago. It was enough of a pain not to want to do it to a brand new £70+ loco.
