While we seem to have a horn thread going...

I got my TR3's horns repainted and was going to reinstall them on the body.  
I decided to check them out first & discovered that both horns 
sound like "      ".

I took the domes off.  That provides access to a coil & a set of oxidized 
points.  I tried applying voltage to the other side of the points but there was 
no mechanical movement.  I suspect the diaphram that is supposed to vibrate is 
seized.  There is no easy way I can see to disassemble the horns farther.  Is 
there a way other than grinding off the tabs at the edges?  

I also noticed that the TR3's horns draw more power than the identical looking 
TR4 horns and wonder if the new replacements draw less.  Since there is no horn 
relay in a TR3 and full power needs to be drawn through a lot of wires and 
connections, I would just as soon have a low power loud horn as opposed to a 
horn that takes a lot of power to get more than a squeek out.

So does anyone know how to get horns with frozen diaphrams working again?  If 
its too much of a pain, suggestions about low powered loud horns that look right
or would look rightish if I glue my horn domes on them would be appriciated. 

 A loud functional horn is important to me.  If I notice an oblivious person 
aiming at me I want to get their attention before the cars try to occupy the 
same space.  It would also come in handy if I get stuck behind slow snakes ;*)
