Chubb Combination Lock

Got this Chubb combination lock. It has EN1330/magic module format. It is the lock from ebay. It seems it was assembled from two locks. The back cover is from a lock where someone has drilled the fence of from the top. But as long as it works ...

Does someone know its model number?

What dial spindle would fit? The normal S&G / LG / UNS 5/16"-40 is to small. The Kromer M9x0.75mm seems to be slightly off. Don't want to force it in.

Has somebody manipulated it? It is a Group 2, but there is no normal contact point on my lock because the lever sits to high. The nose slightly touches the drive cam maybe halve of the rotation.

Cannot see the colour of the lock case from the picture, if it is a light grey case it is probably a chubb 7l05, if a black case it is probably a chubb 7l08

Re: Chubb Combination Lock

Got another one under the name of 7L08 already mounted on a plastic stand. This one not drilled, but I presume it was thrown out of a safe due to problems. The spring pushing the ball to hold the bolt is broken. This leads to the fence lever getting stuck between drive cam gate and case. It makes manipulation also extremely difficult because a moving bolt means a moving contact point. Had the lock manipulated after 3 1/2 hours without noticing it, because the bolt moved so easily. Next manipulation after the lock is repaired.

And tomorrow dinner with a fully professional (and legal) cracksman.

Re: Chubb Combination Lock

Are there two different 7L08? My two locks have cams of the same diameter, but for one it is clearly to small as the lever nose never touches the cam. This one has a thinner case.
