I recently acquired a real early Navy Arms/ Uberti Yellowboy....serial number 2X, in 22LR. Most folks don't know how the repro Yellowboy got here in the first place, so here it is.
In the early '60s, someone at Winchester was wondering what they could do for the Winchester centennial and the idea of bringing back the '66 was conceived. Winchester was afraid to tool up for it, so they went to Navy Arms and Uberti who had been successful in bringing back cap and ball revolvers and the Zouave rifle.
On verbal agreement, Uberti started work and began tooling up for a 22 cal. Yellowboy. As Uberti progressed, Winchester got cold feet.... they didn't think thy could possibly sell enough to be worth while...and they backed out. Uberti and Navy Arms had a lot invested in the project and decided to continue rather than suffer the loss. All of the associated intrigue and politics caused them to fall way behind their original schedule.
As 1966 drew near, Winchester realized its mistake and tried to do something, but between time lost and bad feeling, it was too late. Navy Arms and Uberti eventually introduced the Yellowboy in 1967.... a year after Winchester introduced its '66 .... a 94 with a brass plated receiver in 30-30 (in 1966). This began their string of "collector's and commemerative models.
My low number Yellowboy, one might say, came from the first litter.
