"Scotty's" Rim Cylinder.

[Mad Mick]

I got an old Scotty's rim cylinder from a door on the scrap pile at work. Having cleaned and lubed it, then picked it, I wanted to strip and repin it.

After picking again and unscrewing the tailpiece, the plug would not come out...it moves about a half mil, then becomes stiff. The cylinder has pinning holes at the bottom, which are blanked off. Regardless of this, I feel that the plug should come out. Is there anyone familiar with this lock brand who could suggest something I may have missed?

Thanks,
Mick.

P.S. Since I don't know where this lock originates from, I didn't know whether this post belongs here, or the European section. Mods, please move if required.
