Brass side draft carburetor

I bought a brass side draft carburetor 12 or 15 years ago at the Chickasha swap meet and it has been sitting in my garage ever since. It has a 1920 patent date on the lid and seems to be complete with the ball elbows and choke lever. The price tag (still on it) says $200.00 but I'm way too cheap tho have paid that much for it. It is on offer for $100.00 plus actual shipping charges(it weighs about 8 to 10 pounds). There is a small crack in the lid, about 3/4" long running toward the center but it will patch. Let me know.
