My '48 started its life in eastern Montana and I'll bet the gun rack was installed within its first tank of gas. The rubber has rotted but it might otherwise work. I hang a baseball cap from it.
Do real Saddleman seat covers still come with with the slot for a rifle along the front of the seat?
By the way, my 1948 Accessory List shows an Umbrella Carrier for $2.25.
I've had a couple of the 'saddleman bottom seat covers' that had the rifle pocket on the lower front. Step out, reach in, grab and slide the rifle out of the pocket. Haven't seen a new one available for years, but haven't looked.
Oh..... the glorious past.
