I found this pair of three in one oil bottles recently,i didn't know there was such a thing.i always thought three in one oil was only in a can.These must be the oldest of them.anyone have any info on the history/value/age etc.?
You are correct on them being one of the older ones. Here is a free sample on ebay. Three in One
Regarding value: They seem to be too common for people to pay alot of money for. Maybe $1 - $5 depending on the right person. Might fetch more if you included them in a set of other aqua meds.
Here is a cool thing I found out on the forum. Some religious people use them for baptism water bottles. After the baptiszm the family gets to take some extra water home in them. Three in one...the trinity. Hope this helps. Ben
