I know it is hard to tell from this picture, but does this combo work? The setting originally held a 2.83 ec. It is my mom's. I was wondering if I could set my new mrb in the setting. I was thinking of resetting the ec into something different to make it my own. Not sure whether the proportions look ok. The mrb is a 1.67, so much smaller of course. Here is a picture . Thanks everyone!!
