Pics: Hand operated Windshield Washer pump?

[left_coast*9]

Help me out guys, I think this was installed in my 57 oval rag.

Here it is with the bottle I have. Would these have been installed together?

I assume that 1) The pump would have been mounted on the dash, 2) installed by the dealer. Correct? The pump has SWF - Germany stamped on the rim. The pump rubber is pretty toast.
I guess I am looking to find if this unit is correct for my year, is it rare/valuable, and lastly, is it worth rebuilding and running in my restored Oval Rag? Thanks guys!

That's the style of wiper/washer switch they used in 1961, but with screw terminals on it for the earlier models. I'm not sure when those were produced. I've got an NOS one just like that (the switch/pump- the tank, I'm not so sure about.) I do know that the 61-only Bug setup used a "clear" vinyl hose like the one you have shown, and the cap on the 61 bottle looks like that too (entirely different shaped tank though otherwise) Not shown in your photos is the special two-ball gravity valve needed to make that pump work - do you have one? I'm not sure if it would be different from the 1961 style, which looks like this:

For what it's worth my 56 ragtop has the same type of system installed in it. Looks like it's been there forever. Same type of bottle, althoug the one in my car looked a bit flatter in the middle. The switch was mounted to the left of the speedo, midways up the dash but mine had no wiring on it, just a pump. The wiper switch worked indepentantly. The bottle goes behind the vertical quarter panel brace the hood support bolts to. The tubing was black rubber on mine and the valve was also black rubber/plastic. Thats all I remember about it, hope it helps somehow.

Thanks for the responses, guys.
Glutamodo, interesting, no, I don't think I have a two-ball gravity valve that makes this work, but will double-check.
Does anyone make aftermarket replacement parts?
I would love to hear from more of you. So it sounds like mine might be a year-correct for 57. Pls speak up if you don't think it is. This is obviously a manual setup. If I choose to restore this unit and use it, WILL IT ACTUALLY WORK WELL? Does anyone have a setup llike this that is functional ? Are you happy with it? Thanks!

Will it work well? It worked well enough for VW to install it for a whole model year before they went to the air-pressure setup.

I was digging around in the Classifieds just now. I see two of these kinds of switches but both of them are the 61 style with push terminals, not with tabs to accept screw terminal ends like your switch and my NOS has.

I found a better photo of my NOS switch, along with the hose and valve pieces that came off of my very first 61 bug. I called it a gravity valve becuase it works best when it's oriented correctly, it basically only allows suction from one fitting and pressure to the other one.

And then there was this lone photo in the 61-65 Bentley that happened to show the valve:

I've never seen just the rubber bulb off of one of these types of switches for sale separately before.

I was hoping that RareAir or someone else who's big on period accessories might chime in here - My thought has always been that the ones with screw terminals were offered by VDO as retrofit type of accessory when they started making them for VW in August 1960, replacing a similar setup they had prior to that. Looking in some Accessories brochures I see this one from 1960 that shows a more primitive looking switch and valve:

The one in that greenish accessory picture there is the exact setup mine has. Been trying to find a replacement nozzle for it forever.

It actually had a circular chrome domed top with a rubber seal to the cowl and 2 jets, the rubber deteriorated and the top fell off. Hell I'll check the site you suggested, as long as the it works and looks similar, thanks!
