Vintage Double Hose

Continuing my Nemrod Snark DH reproduction parts, I'm now looking at the LP seats...

These are co-moulded around a metal shaft and X shaped stabiliser ribs, and I need to understand what this substructure looks like to create accurate RFQ drawings for the metal and co-moulded rubber parts.
Food grade silicone rubber should last longer than the originals.

However all of mine are still in serviceable condition and I don't want to cut one up!
Anyone got a trashed one they can either send to me or remove the rubber from and accurately measure please?

Found one to pull apart!
The X piece appears to be a bronze investment casting, with a stainless shaft crimped into it... then the rubber co-moulded around it.
Which makes sense for volume production.

I know this is a year old, but it looks like the VDH forum still has some active users.

You can use an early LP poppet if you drill out the poppet shaft hole in the little retainer/cover. The old 2 piece part can be refreshed with a new seat puck. I made a new poppet from a USD LP poppet cup with the shaft cut off and drilled and tapped for a new shaft. I also made a new cover so I didn't have to ruin an OEM part.
