69 washer bottle marking

[Danzo]

Has anyone observed this? Looks like a K inside a circle. Non RS.
Thanks, Doc.

Where on your bottle is that marking?

Can't confirm mine is original, so won't comment. But your image file name suggests it is from an RS?

Do you know why a washer bottle for an RS would have different mfg marking than a non-RS?

With the 1 2 3 pints facing you the marking is on the right side lower portion. The file image is rsz for resize. This bottle is from a non RS.

No, but Danzo stated 'Non RS' in the original post, hence why I asked about the file name (which he clarified).

I took a quick poll of my stash, the "K" appears to be later GM production, as it matches the 2 NOS versions I have. Original production bottles appear to be marked on the bottom only, a "C", at least two different sizes, 1 marked "D F" or "P F", one marked on the side with a "BP" (which was on my '68). I can vouch for one of the "C" bottles (from my X77 since '73"), the other was on my Z11 (from '94, looks to be the same age as the X77's bottle). I can't account for the '68 bottle past '96, the NOS versions have been in my inventory since the '80's. My best estimation is likely several vendors, like we've seen a lot of peripheral (non-GM produced) parts.

Bad lighting in the garage - I apologize for the images.

Steve
