Looking for info on this lock.

I have been able to pick it and I know is Corbin Lock Company, A friend gave this to me in college because she lost the keys. I don't figure it has security pins or maybe my feel for the lock is better than I thought. I have picked it a few times, not as easy as a master lock but I have gotten it. Also I notice maybe a makers mark in the 2nd pic looks like a bird to me like a sparrow.

Corbin lock, pretty sure it is a Master Ring lock. It has two shear lines, so when you pick it, you must pick all pin stacks to the same shear line for it to open.

So for a beginning picker is this an easy lock or middle of the road? Many of these I see are set as military locks. It not a fast pick for me but I can pick it. Any way to find age of this?

Corbin made well made locks with good tolerances. Definitely better made than a Master No.3 and more of a challege to pick. I wouldn't call it a beginner lock, but a good lock to learn on which will give you good feedback. As GWiens2001 mentioned, this uses the Master Ring cylinder design which offers 2 different shearlines, so picking will be more interesting. Age wise.. I'd say 1970-1980 but that's just a guess.

Photos aren't showing up for me, so I can only speak to master ring locks in general, not yours specifically.

I'd agree a lock like this would be a solid intermediate pick. Good tolerances; with MR locks, you will occasionally find spools, though not always.

Having picked a lot of these, I haven't found the MR sleeve complicates picking to any noticeable degree. Directly tensioning the master shear line is near-impossible, so pins don't tend to bind or set there. I've found they pick much like a standard Corbin.

So far picking this I've found that I have to have light tension. A real touchy lock, but a fun pick.

I noticed this issue with another of your posts, pictures work for 1 day and then Im not sure if you're changing permissions, but the photos no longer display here. Does google allow you to make a public folder that is always public and put your photos in that? I personally use imgur.com so that it is easy to upload and no need for dealing with google's or dropbox's permissions.

I may be seeing it incorrectly, but looking at the photos I'm thinking this is a single shearline Corbin padlock. Some locks of this type have the master ring sleeve, which is visible around the plug, and is distinctly separate from the lock body. Others have a milled bevel around the plug that is still part of the lock body. They can look similar enough in photos that I've mistakenly purchased one of the latter off of eBay expecting the former .

Like I said, I may be seeing this incorrectly. Both the MR and standard types of these locks pick about the same, at least in my experience, so from that standpoint it doesn't make a huge difference.

I'll look into that TY

Definitely not a master ring padlock. Here's a video with a similar lock(maybe similar age?).

I'm going to correct myself here - after opening 15+ of these in my picking life, I finally came across an MR that picked to the master ring shearline yesterday. I was surprised, to say the least - wasn't even sure that was mechanically possible.

It's mechanically the same as picking an SFIC to control. It's probably easier to get to control by luck than it is skill.
