Congrats on a couple of very nice WSP, HD Smiths, 3DFlyer! I wasn't aware the Factory ever offered them in mass order with such as "high blue"! Itself, very nice! Comparing your SNs against my couple of 'civvie' models, noting: S 109515 & S 142072. Respective pix below!
As this Thread exemplary, an appreciable recurring body of material associating this model particularly in WSP. context. Wondering if perhaps mine might yet be of some such LE lineage too. That would seem the principal market for this model/config.
Nothing re my 'couple' to suggest any such association whatsoever. Moreover, too many of my other Smiths yet in 'someday letter' queue...
Thanks for sharing a 'fine pair'!
Best!
John
