Ebay washer bottle?

As I was cruising ebay, I came across a Windshield washer jar.

Was this a option or afterstock?

Kinda interesting.

Very Cool, looks like a repackaged Anco setup. More than likely an add on as the paper said "for installation on all models"
Would make a very nice add on to any truck, in my opinion.

doesn't come up in my 40s-50s parts catalogs, but I don't have an options catalog, probably a dealer upgrade option from IHC,

there is a GM version of very same thing on ebay, so it was Anco multi application like Lloyd says?
