I have a Winchester 9422 Yellow-boy in 22LR. I have not been able to find it in any catalog, Blue Book or online. Does anyone have any info on this rifle? production dates or numbers produced? Thanks!

I received some info that there was supposed to be a production run of 500 guns, with special serial numbers starting with YB. I have also heard others say they have seen these without the prefix in the F75XXXX serial number range. I still have no info on who they may have been made for. A recent rifle sold on Gunbroker for $1225, only 2 bidders. Mine is F753XXX and came in the brown box of late production Winchesters.
