Ben,
It looks like a 9/20 frame extractor. I count 5 slots in a quarter section.
Fuzz,
I just take my extractor outside, after I used a spatula to get as much honey as possible out, and use a garden hose with a good nozzle and wash it out.
Honey completely dissolves in water making it easy to clean. You will probably have to scrape off a few spots of wax and propolis with your finger nail.
