Pope EL37

I recently came into three Pope EL37. The bottle is stamped Made In Holland but the production code is for Blackburn Mullard plant. The getters on these tubes look like wafers or a capsized boat or something. I have examples of Mullard EL37 and all I have seen have hoop getters. The Pope tubes are smoked at the top. The production code on all three is R61B6K.

I'm guessing that these are later production because of the box printing and bottle logo but that may not mean anything. I'm interested to know more about these tubes and the EL37 in general. I have two amplifiers that use them and I really love their sound.
