Thanks for this really useful document. As you suggest, Eddie Parker was due for distribution in February 1969, a time that ties in with the hand written dates on the four copies featured in this thread. Summit distributed in the Chicago area, a market of considerable potential - this in itself is significant as it boosts the numbers of the record pressed in addition to the Detroit quota pressed by Archer and speculatively, the bulk of the pressing from Nashville which surely was distributed from that city.
Of course it would be interesting to know if Summit distributed Archer stamped stock or WME stamped records! Anyone out there who bought Eddie Parker in Chicago during early 1969?
