On the left is the [020] embossing without a vertical bar on the outside of the skirt.

On the right is the [030] embossing with a vertical bar on the outside of the skirt.

They are from the same mold as evidenced by the matching mold irregularities on the inside of the outer front skirt. [020] apparently came first, and they later added the vertical bar. Both have 41 drip points. Based on the SDP, glass quality, known colors and mold characteristics, I believe both of these may be Hemingray products (and the [010] MLOB version is not).

This is the first [020] I've seen to date, and also the first 210 SDP I've seen with amber swirling. Maybe I've just been unlucky all these years, but I've looked at many, many SDP 210s and they all had the vertical bar. I'm curious how many others are out there!
