Stromberg R-1. Don't know much about these carburetors or their value. There's one on eBay with a buy it now for $99 but I know that's not always a good gauge. I'd trust someone's advice if they're willing to give it but I'd expect somewhere around that price. Feel free to make an offer. I haven't taken it apart but it appears to complete just not 100% positive. Let me know if you have any questions.
