Thanks in advance for any assistance and information you might provide.
I've recently acquired a vintage multicellular horn, but am unable to make a confident confirmation of model or manufacturer. I'm inclined to call it a 1203-B and call it a day... but I'd like to build a mono, two-way speaker around this component and therefore need to be able to reliably consider compatibility issues.
There's currently a similar "Very Rare 1940s Altec Tar-Filled Horn Model H-1203B" on Ebay, and I've had some exchange with the seller who has provided dimensions for the item available for auction. In addition to a few dimensional differences, the welded mounts on the sides of my horn are different in size/location, the joint between the throat mount and horn are different in appearance, and there is a difference in cell mouth construction between the two horns (his are smooth, mine have seams).
Dimensions are as follows:
+Ebay "H-1203B"+ (I cannot comment as to measurement accuracy)
Throat mount (exterior): 5" x 3 1/4"
Throat mount (interior): 3 1/4" x 1 5/16"
Horn width: 42 1/4"
Horn depth: 26 1/2"
Horn height: 16 3/8"
+Unidentified Horn+ (All measurements double-checked for accuracy)
Throat mount (exterior): 5" x 3"
Throat mount (interior): 3 5/8" x 1 1/8"
Horn width: 41 1/4"
Horn depth: 26 1/4"
Horn height: 16"
Photos of the unidentified horn attached.
In short, it would be helpful to know what I've got on my hands so I can hunt down an appropriate throat and driver! Age/era might be nice, too, just in case I want to be a stickler about historical accuracy...
