1944-D Lincoln Cent - RPM, But Which One? New RPM?

I've probably spent way too much time staring at this 1944-D Lincoln Cent RPM, but it has me stumped.

It clearly is a D/D ENE. It has a distinct vertical line through the primary D, and the secondary D is visible above and east of the primary D. I cannot find a listed D/D North, Northeast, or East that has both the vertical line and the amount of separation shown by this RPM.

There is also a weak vertical line south of the interior of the primary mm, accompanied by a weak curve to the east. While not clear enough to be sure, it could suggest a third mm punch south of the primary. I can't find any listed variety with a secondary E/NE and a tertiary mark south.

There is also a very weak diagonal NE-SW line immediately west of the primary mm. That could be a die scratch (probably) or possibly the remnant of a fourth, tilted mm (less likely).

This RPM lacks many of the die markers for the most likely suspects.

VV RPM-009 (Wexler's WRPM-013) is the closest, but that coin's line through the primary mm doesn't extend all the way and its secondary mm is not separated as far east. My coin also lacks the obverse and reverse die markers of RPM-009/WRPM-013.

I can't find any of the non-CONECA parallel listings on coppercoins.com or doubleddie.com that are close to this one.

I'd sure welcome any input.

Here are the obligatory mug shots:



And the date and mm location photos:



And two closeups of the mm. The angled shot shows the RPM best.



I have additional photos and can sure post more, if that would be helpful.

Thanks much!
