I can't agree there. I don't think it's time for IRM to throw the towel in, just yet.
If China do something stupider than usual and get sanctioned, that may have an impact on output, but I do not see demand drying up without a mitigating factor like prices being tripled.
Back to O gauge, yes, definitely fanciful, definitely not likely to be on the IRM radar at thr moment, but...
If somebody had told me ten years ago that the abundance of high quality RTR models we now have was likely, never mind definite, I'd have laughed at them.
And, I'm probably not the only one.
