HP35 V2 surprise on auction site

[vk6ti]

I recently won a HP 35 Version 2, on a popular auction site, it was advertised as a non working unit for parts only, I took a gamble as I only wanted it to fill a space in the HP35 line up, after all it was only $25.
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 ?

Regards
