Frogpatch was in the lighting industry for many years !! It may be familiar to him !! You got the time period right but that's about the closest you will get !! Always try to get the era right rather than the year,, same lamp may be made once then reissued at a later date !! Unless a very high end lamp or by a designer there is usually no name because the parts are made by several different companies !! One does not usually do it all !!
