I have been waiting for a pristine one of these to come up for sale but it hasn't come along yet so I picked this one up. I just love these dials and wanted one in each of the colors they came in. I believe this is the Her Excellency "M". Thanks.
Her Excellency "M" ads
As with the "H" I posted my thought is the yellow was "M", pink "N". Here is an ad with "N".

Thank you : )
The dial sometimes throws me on these, as they could themselves be another variant.
All the adverts I'm seeing have the 'M' with a standard numbers dial.

I do agree that there could be more variants on these. However the "L" I posted from the Her Excellency line seems to be "L" regardless of which dial it has.
Found an ad with this dial. I think this is the yellow dial because the pink dial and yellow dial are different. Unfortunately it doesn't not have a model name. But at least it shows the dial/case combo here. 
1947 Her Excellency 'M' works for me.
