This explains the origin of some bumpers we’ve seen on trucks. I *think* I’ve also seen that winch a few times. Also, it appears that Kelly Manufacturing was a reseller of them.

“”Mobile Bumper Inc.” Brochures for Willys, Jeep and all Pickup Truck lines, by the writers and illustrators of Mobile Bumper Inc., Indianapolis Indiana. No copyright date, but the a Price List included is effective February 15, 1957. Published by Mobile Bumper Inc. NOT Ex-Library. No ISBN – there were none in those years. Note – the photos you see are of thess brochures – no ‘Stock Photos’.

Three splendid brochures and a price sheet, various sizes, drilled for a 3-post binder (binder not included). A trifle of roughening around those holes after 2/3 Century. Lots of good Illustrations, splendid information for these 1950s-era Jeep and other brand aftermarket accessories. Here was the equipment you needed, and a bit of ‘How-To’ for improving that vehicle.

The marketer, Mobile Bumper, advertised these items for sale – interestingly, the price list is titled ‘Mobile Bumper’ but was printed by Kelly Sales, Charleston WV. In many cases equipment for aftermarket Jeep applications was made in Toledo Ohio, home of Jeep, and was marketed by other companies. Not sure if that’s the case here.
