OOPS - yeah, Loewy, not "Lowry."

I got my truck spacing info from the same sources as Missaberoad.  Back when Matthew Myers was thinking about doing an FM shell for his Shapeways store, I suggested that the VO-1000 mechanism was "close enough" and I still think that, but I'm not particularly a rivet-counter kind.  I suspect that if Atlas ever did one, they'd do a new mechanism based on the VO-1000 design, but with the correct truck spacing.  I'd happily take a single shell version, too, but again some folks would complain, and the Loewy version does look substantially different from the "simplified" version.  So maybe two shells: one Loewy and one simplified?

The NKP had several of the FM switchers in all versions, and I've been tempted by the Shapeways shell; but I've got too much going on right now to pursue it.  I was sure that when Bill Denton completed his stunning Milwaukee units from the Shapeways shells (see the other thread on Shapeways FM shells), Atlas or Bachmann would immediately produce one  :D  Wrong . . .

Those wheelbase figures are 8 feet too long. According to the PRR.railfan.net website the  outer truck wheelbase numbers are close to what your website stated.
The VO-1000 and FMs should be 25'6" center of truck wheelbase, and 33'6" at the outer axles.
This would also put the other measurements at 22'6" and 30'6" as well, which would be more in line with our model dimensions

That's what I get for turning to secondary sources...  so both those sources are incorrect...

This CN Diagram of a 1955 mid production unit confirms the 25'6" truck centers, and if the later units are indeed 3' shorter then they would be 22'6" as you say...

Thanks guys for hashing this all out while I was at work! Glad to see that I wasn't misremembering (in this one case).  ;)

Best wishes, Dave
If you lend someone $20, and never see that person again, it was probably worth it.
