Brian Morland MLA Hon This one Gary is holding up was donated to the HoL Archive by Peter Wosahlo - a Government locksmith at the Houses of Parliment, and is signed on the back by Ralf Perryman.
Gary Stephenson I have a load of drawings from Chubb and Tann, some of which are large enough to paper the walls with, and loads of smaller service and modification info, the paperwork flying about at one time was phenomenal.
Gary Stephenson I will put up a selection of them just to show the scope of documentation at one time,
Gary Stephenson I think the costs/prices were to the safe depots and would have been marked up about 150 percent to customers
Gary Stephenson time allocations, I remember one of the engineers saying most of the time these could be done much faster so they got to go home early as they could fill out their timesheets with a days work of work early.
Gary Stephenson just a selection to show the different stuff, and even different screw fixings and part numbers got their own paperwork so there is a lot of dross to sort through before you find an interesting tidbit, some of the drawings I have of cash safes and strongrooms are probably 4 or 5 ft tall.
Cepasaccus Nice! I saw in the parts numbers list a 7K51 and a 7L51. What is the difference? I always thought K is for key lock and L for combination lock, but this 7K51 seems to be also a combination lock.
Gary Stephenson rather than a full lock with L part number, it is probably a part for a combination lock
