HP Seat Identification

[rsingler]

Hey, guys. Can someone ID this for me? It's a little over 1.5" long.
They're nickel plated, which probably puts them after 1991.

Was in a pile of Dacor parts I acquired, but I can't locate anything like it in my Dacor manuals.
I have three, if anybody needs one. The seats look unused.

Thanks!
Rob

Are you sure it's a HP seat? It may be a balanced seacond stage seat of some kind. Without the balance chamber end, it looks a lot like several other Dacor second stage seats. On those, the lever fits in the ring near the large end and if this is a HP seat, why would that ring be there?? Finger nail test the oring and seat face, if they are hard it's a HP seat, if not then odds are that is a second stage seat.
