Steve Guttag identified these as the 'Simplex W'. They're apparently a part of an Altec sound package (including little green Altec Amp) that went with a Simplex projector package.Somebody shrank your horn. But joyriding stagehands haven't damaged your bodywork, so you're ahead...

Ok here you go Scott..What you have/had are International Projector Corp's XL532-311 Speaker system. IPC offered 6 different speaker systems. The XL532-311 consisted of: A high-frequency horn LU-1085 (aka Altec 805) or the LU-1086 (aka Altec 1005) A High Frequency Driver LU-1104 (aka Altec 288B) An appropiate throat for the HF horn you have. An LU-1121 crossover network (I don't know of a direct Altec cross, on this unit you shorted two posts if you had two HF drivers to add an additional series capacitor) The LF cabinet is the LU-1106 large cabinet with a single LU-1081 (aka Altec 515) driver. Bill Hooper's speaker is nearly identical but it is the XL536-322 since it has the double 15 cabinet LU-1107 and the LU-1087 3x5 horn (aka Altec 1505). There should also be two HF drivers mounted to a y-throat. The next level up got you two HF drivers mounted to a common horn (y-throat) and the super-primo-deluxe had two w-cabinets with dual drivers in them and the double driver HF unit with a 3x5 multi-cell horn.
