Original Horn ID and operation questions Options

[Literati914]

While reassembling my ‘72 project it’s come time to figure out my horn situation. I found these two horns in a box and am not sure if one or both were original to the ‘72. My car does have the wiring for two horns but I can not remember if both of these were on it before disassembly. I kind of think the smaller one was on my ‘74 parts car.

Either way, I need to know: are these two normally used in conjunction with one another as low/high (quiet/loud (IMG:style_emoticons/default/biggrin.gif) ) - if that can even be determined without part #s? If they are both of the same volume I guess I’d just be using one - or do two quiet ones make a loud (IMG:style_emoticons/default/confused24.gif) Are there any knowledgeable horn experts that can help? Thanks

The horn on the left is an early stock Hella horn as noted by the screws around the perimeter....they can be taken apart very easily to repair...Later Hella horns have rivets which you have to drill out and replace to repair....Stock was one horn and second horn was an option and later added into the "Appearance Group" trim package....the 914-6 came stock with two horns..
I think the two horns Hz was 400 and 335
