Here's another EPDG Owen with the spot on his sleeve.
EPDG-3.jpg
This one puts the number of EPDG subjects with the spot at 3 out 5
and Scott has a new PD150 with the spot up on ebay now that puts
the number of PD150's with the spot at 14
https://www.ebay.com/itm/T206-Owen-F...4AAOSwZrhah06B
but I still haven't found any PD350's or any other 350 backs with this
spot as a matter of fact I still haven't found any of the variations that
are found on the 150 subjects on any 350 backs.
There have been discussions before about the EPDG and Old Mill
printing timeline for the 150 series and from the research I've
done I think they might have been done in this order
150 series with EPDG backs
150 series with PD350 backs
150 series with Old Mill backs
350 series with PD350 backs
350 series with EPDG backs
350 series with Old Mill backs
