Code 83 is .083 inches high. Therefore, the difference is .017 inches.

The loco number question is more complex as there are (at least) two different schemes:

1. In the US, the Whyte System counts the wheels of each axle group on the loco, e.g. a wheel arrangement of oOOOO = 2-8-0, or “Consolidation” type; likewise,
ooOOOo = 4-6-2, or “Pacific” type.
Other countries may use a different scheme.

2. The “Official” number painted on each loco may depend on the parent railroad, the assigned “class” of locomotive and/or the order of purchase.
For example, the Denver & Rio Grande RR classified its (Narrow Gauge) Consolidations (2-8-0) as “C” beginning with C-16. The Mikado (2-8-2) as “K”, beginning with K-27 and numbered from 450.
