We have guys out here in New Mexico that have been collecting gas & oil stuff for about 20 years or so. Long before I got the bug, and I have talked to them about these Malco pump plates on number of occasions and They say they never made them. But there could have been maybe just one jobber that had a few made or maybe some were made for the refineriery in Arttesia, New Mexico. But every one of these that has come up for sale was out of Texas. I don't even think Malco was in Texas. But these things sure look real to me with the gray porcelain back and the rack marks and the split grommets. So who knows. Would think a beat up one would turn up some where.
