Servicing a Silca Impero frame pump?

I've got an old frame-fit Silca Impero pump with the Campy head that came with one of my bikes, and I'd rather like to try to get it back up to spec. It's never really worked that great since I've had it, and I presume that it could probably use new washers and gaskets at this point. Anyone know of any sort of disassembly instructions or an exploded diagram out there? I'm hesitant to just start randomly twisting things in hopes of opening it up, lest it explode into a million pieces on me.

There's not much to those pumps. Replacement gaskets for the pump head are available if your's isn't sealing well:

The leather gasket inside the pump body seldom needs replacing, but it can dry out and allow air to blow past it. If this seems to be happening, simply unscrew the cap where the piston enters the pump body and pull the whole thing out of the pump. Use your fingers to work some oil or grease into the leather gasket and re-install the piston into the pump body. It should be good for another decade or so of use.

The knurled plastic ring at the handle end of the pump body unscrews, allowing you to removed the plunger rod. Sometimes they can be a little stuck, so go slowly and maybe use channel locks type pliers and pad the jaws.
