A little later I acquired a Sierra #38 and happened to notice that it was as big as the #201. Slowly the facts and observations were pieced together and Irealized something was wrong. The Sierra tender should be the same size as the #201's but was actually bigger. Finally I measured the #38s drivers, nominally 56/57 scale inches, however the #201 had 51" drivers. The protypes had the same size drivers. The PFM model used drivers that were at least 10% oversize and the builder simply expanded the rest of the model to accomodate. For other prototypes I've found that driver size off by a couple of inches, or driver spacing expanded to accomodate oversized flanges, can ruin a model's appearance and value to me. Thus the ethical dilemna, should I tell potential buyers or just assume, "That everyone knows..."
Also note that the PFM ATSF 4-6-4 was over-sized. Just put it next to one of the later Key versions and see the extreme difference. Of course it's very much cheaper in price than the Key versions.
For me time stopped in 1941
