jbl 2440 2" throat with horn unknown???

[purejazz]

I have a jbl 2440 driver which is a "2" throat , I have some horns that are bi radial . The horns are not 2345 or 2350 , the horn has a 2" throat and mounts to the driver as it should . however I do not have any idea as to what JBL horn this is , I was told it is an jbl horn but there is no posting of this on the spec sheets that I have found to date . The horn looks pretty close to the 2345 but instead of a 1" throat it is a 2" it is also heavy cast Al .
I would like to know if anyone can tell me anything about this horn , the specs and model . In addition to for driver and horn recommended 500hz or 800 hz crossing point , any info would be great.
