I believe that mine is the Champion Spin-on from Aircraft Spruce.
I have about 250 hours on it - very happy with it.

The FM oil filter is available from AC Spruce or an authorized dealer, can't get it direct...

The F&M filter adapter is great it's a full flow filter and makes it so you can look at your oil at about 25 hours on it and it isn't totally black.  You could run you oil to 50 hours but I've been a firm believer that oil is cheap insurance and change around 25-35 hours(or 4-6 months).  The only problem I see is when you take the filter off the oil is hard to catch since it's over the nose wheel strut and it makes it hard to catch so you spill a bunch on the nose struct and tire.  The best part is it doesn't have any hoses that could leak and need replacement.  I watched a Comanche fry it's engine after a remote oil filter hose leaked all the oil out. It was all gone about the time the aircraft was a couple of hundred feet in the air and the oil preasure went to zero and the owner did the quickest turn around and still had to buy an engine.  There is a lot to be said for one that attaches right to the engine.  Also now that you have a filter you can put magnets on the canister to lower the size of ferrite particles that are going through your filter. 
This increase the your filters effectiveness but you have to have very strong magnets.  A while back someone was making a magnet for the filters and was selling them on ebay.
