Master locksmith Harrow said a 3G114 would really only have 4 lever configuration with 8 lever heights so the maths would be 8x8x8x8 = 32768 possible heights less the MACS but chubb will add another x8 to there maths as they do produce locks for some safes that use a 114 body that do not have symmetrical patterns so all 5 levers are different so there calculation would be 262144 different combination available on their locks.
 
This is the same formula they apply to combination locks so a 3 wheel lock would be 10x170x190 = 1,000,000 possible combos 4 wheel lock would be 90x110x104x150 = 100,000,000 again macs apply to the fact that the last wheel should not be parked in the zone.

there are some short cuts when comes to manipulation of a combo that the older locks can be parked on a 2 1/2 number increment(so say 10, 12.5, 15) so if we take 100 numbers divide it by 2 1/2 = 40 so now the power of combinations on a 3 wheel would be 40x20 = 64000 or a 4 wheel 90x80x30x40 = 2560000 pity all the new ones have less tolerance’s.
Could the control lever be called a monitor lever, which was an old 3g114 type lever with a big hook type tail which blocked the keyway if the lock was half shot , seen in some of the early Chubb wall safes.

Nope the locksmith Harrow zone is always the same place as long as the person fitted it put the spline key in the right place, the forbidden zone, is basically. Don’t set the last wheel in over the drop in point" this normally on an S&G 6700 between 9 - 14.

So I believe the recommended is don’t set the last number between 0 or 20 so the combo would be 19x190x100 = 800,000 possible combos so a 4 wheel 10x150x100x70 80,000,000 possible combos so a 3 wheel on 2 1/2s would be minus the 20 are 48x47x31 = 49600 or a 4 wheel on 2 1/2 would be 46x49x40x51 = 1984000.
 
but I can tell you customers till park them there if they can, the reason its recommended is that when you set the last number if it’s in the forbidden zone you are past the drop in point so the lock will fail to open, you will move the wheel when the bolt is withdrawing take one apart & you will see what I mean.
The manifold drive cam has only 1 direction it can be fitted in unlike the 6700 that has the VD,VU,LH & RH so the drop in point will change depending on the direction it is fitted, but with the Manifold you have not got to worry about the last wheel as its fixed to 0,25 or 75 depending on the direction so the maths would be 103x160x170x5 = 3,000,000.

Bloody hell loads of info. My thinking was as in mla exam q in key only goes in one way and has maybe 7 levers and does not need to be symmetrical. Control lever meaning it keeps all other levers away from bolt stump until set in gate. Monitor is a lever with a large tail that blocked keyway if pick like in the 5 lever fitted to Chubb no5. Just trying to help members out.

Locksmith Harrow was told that came up on the BLI safe exam but they had forgotten there was something about making a key via a scope to an SMP 7 lever S520 lock, personally I’d pick it open instead of mucking about.
