Is there a 7 pin key out there for the schlage C keyway? Reason I ask is because of this practice lock I purchased on ebay.



I can use a 6 pin key with a #9 pin in the last chamber but that's a little underwhelming. Now a #9 pin in the 6th position and a #2 in the 7th would be a little more devious!
Also, has anyone seen these locks in use? I can attest that with radical bitting and security pins these things are quite difficult to open without a key.
Quick intro:
Hey folks! Figured I'd introduce myself and tell you a little about how I got into locks. I've been a machinist for about 10 years and I am currently working as a machinist/engineer for my own LLC. I find that learning new mechanisms has been a boost to my creativity when designing new things for my day job. I got into lock picking after picking my first wafer lock with a paperclip. Since then I've taken every opportunity to learn new locks and techniques for almost no reason other than boredom relief. Gotta spend the girlfriend's change jar somehow!
