antique vintage leather motorcycle gauntlet mitten gloves, wool lined mittens

Vintage black leather gauntlet mitten gloves in a size medium, in very good condition.

We've been told that these are 1950s vintage or earlier (but they're wool lined so they're lambskin, rather than horsehide?) but we don't know much about motorcycle stuff and can't really tell you more about these than that.

They're embossed with an winged emblem (not Harley Davidson?) on each mitten, and the leather seems to be in very good shape for the most part without splits or cracking.
