I didn't take much to "fire it up", ( lucky), and to my surprise it had the 2.02 bug.

Q. I thought the 2.02 bug would have been ironed out in the Red Dot versions,
would there have been many V2's that went under the radar ?

The bug fix offer came out after version 2 starting shipping. I bought my HP-35 version 2 (non-red dot) a couple of months before receiving the free repair offer from HP and took them up on their offer. I still have that in my collection along with a non-bugged-fixed version 2 and a yes-bug-fixed red dot version 1 (i.e., red dot). There are many non-bug-fixed version 2 HP-35's out there. However finding a non-bug-fixed version 3 or 4 should be impossible and if found would indicate some sort of board/ROM swap took place.
