I am selling these 3 cylinders on ebay, and it occurred to me that I know very little about them. I got them on ebay about 6 months ago, from someone who knew no more than I do about them. They have no markings of any kind. I thought maybe someone here might know who made them. I was able to find a blank that slides in which I could key them to...a yale dimple key padlock I have, but they came without keys. They also use a very unusual cam. Thanks for any info.
