Wanted a little project so I decided to buy an older Silca pump from ebay. I bought one that's in rougher shape and didn't cost all that much. I've no idea exactly how old it is, since none of the people selling these things post pictures of the relevant bits for dating. The one I bought has a broken handle. I've found exact replacements online, but they're rather expensive for what they are, so I may just say to hell with keeping it as close to original as possible and put a wooden handle on. I'll post pics when I get it. I'll probably need to purchase some parts for it to get it working well again.
