Seals on outside of front M37 hub

When I disassembled the front right hub for the first time between the spline cap and the hub body there was a paper gasket then a metal framed leather shaft seal. Is there supposed to be that leather shaft seal in there? The TM's don't show it. I thought there was just a paper gasket between the spline cap and the hub like a deuce or 5 ton axle has.

That inner oil seal ( saw post/pic on SS site) should only be on the back as its meant to keep 90w from mixing with the grease in the bearing hub ( just like the deuce ) not needed on the front spindles, someone must have gotten a little carried away. Heck if I remember correctly I found those same inner seals on my M-101 trailer along with the shouldered lock nut that the seal rides on

That's what I was thinking. Haven't pulled the left front hub yet. No telling what I'll find in there. Who knows, the rear hubs may be missing these seals. Thanks and seeing the pics on SS helps I bet.
