    Did you get sorted? I would suggest Mark Bates Associates to try first.

    UELS in England will be able to get them for you Welcome to United Electronic Locks Services Limited these locks are now made under the Mauer label owned by Kaba.

    There are a couple of different Convar locks but I think the keys will work both, best to check though. Does yours have antipressure device?

    Looks like the basic Convar F to me but willing to be corrected. No anti pressure device.

    The operation is similar to the Ratner key changeable lock. Not sure if there are pictures on here if you search

    From what I have found Theodor Kromer patented his Protector in the 1870's. He is supposed to have worked for lock company here in the States prior to that time. The changeable style that is used on the Kromer Convar, Ratner, Chatwood and others, dates back into the mid 1800's, at least here in the US. A 1864 MacNeale patented combination lock is the clearest example but the idea go back even further. Doug

    Here are a couple patents. The 1864 MacNeale isn't as clear as the William Hall of 1865. Doug
