Hot Water, yes we have. But, that was a while back, really before the L-131 was produced. Who knows, now with the L-105 possibly adding to the demand. Nothing ventured. Nothing gained. Seems to me.
And at the price point for the L-131 and now an even higher MSRP for the L-105 perhaps an "over $400" price tag for an "accurate" (your words) might work. Can't hurt to ask.
So, Scott, how about considering one? Maybe you could put out a feeler with a price and see what happens. Noting ventured, nothing gained.
Maybe I've been looking in the wrong places and have surely missed some for sale. But my experience over the past two years has been black steam era "accurate" cabooses are rare as hen's teeth and very pricey. I've seen them go for way over $400.
