Structo Artcraft loom

Can you tell I'm all about weaving lately? I just picked up this Structo Artcraft loom I recently won on eBay. It is a small 4 harness table loom for weaving no wider than 20". Everything works perfectly, I just need to get all the rust off and change the heddles - my weekend project. Hmm, so how do you get rust off??? May take longer to restore than expected. Regardless, I'm excited! Structo was the toy company who made these looms in the 1920's. It reminds me of the Gocco.
