Delco Remy "Sea Shell" Horns

[Spinneyhill]

I accumulated 5 "Sea Shell" Delco Remy horns from swap meets during the '90s, coz I needed some. It turns out they are the wrong model.

 

How can I find the models and what they were used on?

 

There are two pairs (L and H) of one model and one other. The pairs have 519 and 520 stamped inside them on the rim (ink or paint) and the other has 2083 stamped inside it.

 

If I can find out what they were fitted to, they could go to someone who could use them.

 

Is there a catalogue on line anywhere?
