Oldie LRP "E" mill - wind?

[Lonestar]

Hi guys

I have a couple of black cans - blue label vintage LRP mills... the winding isn't spec'ed, but there's an "E" on the can, and if I recall correctly LRP was referring to his winds by letters, like the old Reedy "Mr." series...

Anyone knows what wind the "E" stands for?

Thanks

Paul
