Wylk, I was hoping you might have some input regarding patent searches. Here are pictures showing the bolt retraction connecting linkage. Note however the bolt didn't retract even though the linkage moved into the opening position. To the few of you who are actually studying this post, any ideas as to why this occurred? There will be a little something in your stocking if you get it right.

Mr. McQueen,

Thank you for all your help in the past. I haven't been on this site for a while. I have an Ely Norris Cannonball with the Yale dual locks. My problem is the dials have become increasingly harder and harder to turn. Is there a way to lubricate the two combination locks?

Thanks,

Jody Sims
