German 2307 clones and one unknown horn

[Chevelle]

Hello,

I bought a pair of German 2307 horn clones today. They were build by Visaton and have the exact measurements. The difference is the 1 3/8" thread for mounting the driver. Also the mounting holes are in the same position so it is a bolt on.

As an extra the seller gave me one unknown horn. I think it is made by Coral (?). The mouth diameter is 22mm (0.86"), mounting holes for the driver are 2" diameter, opening diameter is 100mm (4"), length is 237mm (9.4"). Who knows something about this horn ? Can somebody use this single horn ?
