- Options had html set. Perhaps this works better. Here it is again for
another go hopefully less the rubbish.
Conversions are relatively easy with the key.
The lead O as in On3 indicates scale O scale US = Quarter inch to the foot.
The n indicates narrow gauge.
the 3 you show indicates prototype gauge (3 feet in this instance).Some may

S Scale 3/16 inch per foot or 1:64 ratio.
Hope this clears the way a bit.
