Possibly, but I remember more "violet" in 2943 than I see here. You might check the tagging. The tagging on my 2493a is much grainier than that on 2943. Will try posting a scan of my Alice Pauls for comparison. They are 2943, 2943a & 2943b respectively.
Added: The longer I look at your scans, the more they look like you've identified them correctly.
