Can you tell me how to differentiate betwwn a Bauway and Joye LR atty?

I don't keep my gear in very good order--needless to say. Do any veteran vapers(or novice vapers for that matter) know how to visually tell the difference between a LR Bauway and a LR Joye atty?
Thanks

Oops, misspelling in title, edit won't let me change stuff in title I guess. My bad.

Joye LR atties usually have a LR stamped on the bottom. The LR bauway i have has black ring of epoxy on the bottom. It is around the positive post that keeps it from touching the ground. Joye uses a white epoxy. Cant say they are all like that, you never know when they will change stuff around at the factory.

Thanks,Java.
My Joyes have the white ring but have no attys with a black ring. Ahh well, no matter. I'll clean em up, use my multimeter to check resistance and wear them out. I've always been a bit lazy where details are concerned. I'll have to clean up my act when it comes to vaping--either that or find the perfect atty and stick to it. Like thats gonna happen
