    Default John Tann 6 Lever

    The pictures below are of a John Tann Lever lock.

    The lock opens in the conventional manner using the key.

    However, there is a pin/button on the back of the lock, connected to a spring that holds the bolt in the unlocked position. When it is depressed, it frees the bolt & the bolt is shot closed by another spring. It cannot be locked using the key.

    The lock case is stamped 328(second picture, lower left corner).

    I would be interested to find out the approximate age of this lock.

    I have this type of lock new in stock -they are still made for bank tellers drawers-allowing the drawer to lock instantly if the button is pushed but requiring the key to open it.

    I thought that was its intended purpose (cash drawer/till), thankyou for the confirmation.

    Do you have any true left hand versions? I normally now retrofit to a drawer pushbutton lock.
    The ones I see are stamped AGB.

    Depends what you call true LH-everyone else seems to get it wrong and when they dont, then I seem to get it wrong instead.
    Easiest is to say that they are as per your picture - i have a couple at least of them as shown

    I doubt it is of any importance for the locks that Alan is looking to source(handing, and disambiguation thereof seems more important), but the example Alan pictured has the button to shoot the bolt on the keyhole side of the lock case. My lock can be unlocked (only) from the one side, and the button that shoots the bolt to the locked position is on the other side.

    Do records exist to suggest an approximate age for my lock, given it(and key) is John Tann & it is numbered?

    Perhaps the pin is pushed by a stop of some sort such that the door/drawer just has to be slammed shut to lock. This would be faster and would help prevent the bolt shooting if the front button were pushed inadvertantly. I have seen both types in the past but never fitted, they were still in their boxes.

    As I have seen these on old slam action wooden tills and come to think of it on the metal tills used thirty odd years ago I can only agree with the above. That yes there was a brass plate (mounted on the inside) which engaged with the pin and caused the deadbolt to shoot.

    I normally see them on Tann undercounter safes in nat west banks, there is normally a number on the safe that would probably help you date it, same lock but most of the ones I see don't have the Tann name on them.

    The pushbutton lock is the new one I fitted, originally there used to be only the keyhole (now filled in grey but visible) right next to the new button.
    The keep originally had a tab which pushes that tiny button on the back as you close the door. I could not get the exact lock so used the vertical up drawer lock instead.
