Here is a shot through the bases. Since the lighting conditions are less than ideal I thought it might be helpful to include a couple of other 121's for comparison. I'm sure there is a huge difference in glass from different manufacturers but this is the best I can do right now. Maybe there is a McLaughlin expert out there that would share a shot of their collection that would be more helpful. The McLaughlin is the middle piece.

I appreciate all the responses so far. Thanks for helping out a new collector.
