Masterlock 150?

I've been working on this lock for a while, I can pop it open pretty quickly either raking or SPPing, but I was watching some picking videos on youtube and someone said it had spool pins, which I didn't think it had any. So basically I just wanted to know if it did or not. I found that I need to use really light tension, so I'm thinking it MIGHT have some in it.

Well, I've just been fiddling with it and I'm pretty sure that the middle pin is a spool pin, cause when I push it, it causes the cylinder to turn back a little bit, and there is also the thing where it turns a few degrees but doesn't open.
