Did I misunderstand something?
Oh, I think I see what happened.
When I spoke of the McCarty 594 being introduced originally as a Private Stock model, I neglected to type the three characters 5, 9 & 4 before typing the word McCarty.
It also seems that the typo could not be clearly identified by the context either; the context which was heavily laden with those characters 594 repeated over and over as that is what we were talking about.
So, yes, I clearly failed to insert "594" in one of the places where it should have gone.
My apologies for the confusion.
I was speaking of the McCarty 594 model which was originally introduced as a Private Stock model and then later offered as a Core production line model.
I don't know anything about Private Stock line or when it was first brought into existence. That is very interesting about the 1994 bit. Off topic but interesting.
Sorry again for the confusion. I'll try to type more carefully in the future and better proofread my posts so that everyone can follow what I say.
