This is the later type washer bottle. Luis has a '64/'65 and that would normally have a smaller round bottle up on the inner wing just in front of the hood hinges. Uses a seperate pump with an alloy cover. When these pumps go bad the system is usually converted to the later type as shown.
From various other posts I was surprised to find that Volvo sold Amazons in "dry/hot" parts of the USA without a washer system. That's maybe how the bag type got fitted, perhaps by the dealer or an earlier owner. I've got a bag type washer kit in a box with a oficial Volvo part # and info sticker on it. It's probably from the '70s. The kit was made in Japan!
