Check out Greycar and Halcyon Classic Parts. Greycar has gauntlets with cotton or wool lining. They also have some wrist warmers that are very good, prevents cold air running up your sleeve if you are wearing short gloves. Halcyon has gauntlets with cotton lining in several colours. Sizes a bit bigger than Greycar. Quality is good. I usually wear Halcyons, ok most of the time - just occasionally wollen Greycars. What I have come to like a lot is the wrist warmers, extends the use of short driving gloves. Living in a harsh climate I just have to protect myself, neither cold hands nor head are allowed to destroy a trip in the Morgan.
