Near the rear is a innard frame that is similar to the Standard Aerobee, Aerobee 150, and even the WAC Corporal. But the diameter is entirely too large for any of these. There is a chance that Aerojet and NASA built this - but thats totally speculation on my part.
Whats odd is the hand painted E-18 on the rear fins - and even moreso that the E-18's were painted haphazardly along the fin line. Compare the size of the E-18 on fin # 2 & 4.
Allied Signal has an Engines Division in the Aerospace - Defense business. They recently merged with Honeywell. So that might be a clue. Perhaps an email to them might stir up a possible hit.

I certainly don't have access to every missile and rocket image, but even with my larger archive, I can't locate any info or images of this design. Looks like I need to buy the rest of Pete Alway's books - post haste.
Hopefully someone else can clear this up - if all else fails, try posting a message over at Scaleroc, or contact Pete Alway.
Sorry I couldn't be of more help,
