    I found this lock while metal detecting. I'd certainly appreciate any info you could provide regarding age. I do have legible info at keyhole

    Hi Stevebob,
    The info that I have learned on the forum here is that the logo was used by Y&T during the period 1884-1909.
    As for the code, hopefully someone else will chime in with information.
    Regards, Mickthepick.

    it might be a direct diget cut. if it has super pin tumbler on top it's after 1934 that type y was used til the late 40's and se should be the keyway

    The circular part of the padlock that contains the trefoil design is an insert in the casting die that can be changed to allow a customer logo to be inserted in place of the trefoil. In 1929 the use of the trefoil was discontinued and the back side was changed to match the front unless it was a customer logo. While employed as the Key Records Manager at Yale I researched in vain trying to find a record of all the customer logos but did discover the discontinue date for the trefoil logo.

    I wondered why it was discontinued and one engineer made the guess that it was because of the stock market crash that year. It would have been cheaper to produce the inserts for front and back with the same design. Those inserts do need to be replaced periodically so the year and need for economy because of the crash conspired to change, or in this case eliminate, the trefoil logo.
    BBE.

    My catalog measurements are somewhat different for the Yale cast bronze padlocks:
    • 830 Series, 1-1/2" size, 1/4" shackle
    • 840 Series, 1-3/4" size, 5/16" shackle
    • 850 Series, 2" size, 3/8" shackle
    • 870 Series, 2-1/2" size, 7/16" shackle

    Note that No. 870 is still made today.
