Just picked this one up too.
10344103 is a first run based on the range, no debate.

Face plate 187, Back plate 359 is thus established for first run.
The previous note posted above with 10140540 serial has a face plate 217 WAY higher than 187, but on a serial WAY lower than this note from first run. Same for pack plates.
Pretty sure that's a lock to say 10140540 is second run, establishing FP 217 and BP 378 as second run, yes?
