I need an opinion on this one

[Longhunter]

I picked up this bottle at the antique store a couple of days ago. It is 3 1/4" tall screw top. I assume it might have been an iodine bottle (maybe). The shape is SIMILAR to the KO-3 iodine bottle. It has a rounded front with 3 flat back panels. On the center back panel there is a large dot at the top and bottom of the panel. I see a "P" inside a flag on the bottom with "RE PAT 19520 USA" also embossed on the bottom.
Any of you poison guys ever seen one of these?
I can't seem to find this one in any of my books.

See the pics below.

I went to this site:

But I did not see a "P" in a flag or pennant mark listed.

I think I remember seeing one used by Fischer Scientific for a chemical stain. it had a dropper as the patent indicates.

OK..... so that is what the "19520" patent is for.

The patent is for the eye dropper/bottle design
