1800s Macneale & Urban lock manipulation?

[Aralli]

Hey guys I'm new to the forum here but I have from what I understand an old Macneale & Urban safe that uses an alphabetical dial instead of numbers. I was wondering if anyone has had any experience with manipulation on these type of locks and if there's any tips or tricks they could share with me.

On their cast iron fire safes the most common lock has four wheels and the last wheel is connected to the drive cam. This last wheel is most of the time set to K. The dialling sequence is 4R, 3L, 2R, 1L to 'K', R to stop. You should be able to identify this lock by the little play between the last wheel and the drive cam. People like to use words, so trying 4-letter words ending in K is the usual start. My guess is that manipulation is similar to the normal locks, besides the dialling sequence, which is unusual for a 4-wheel lock.
