The listing does not give much detail are they double lipped with the springs fitted top & bottom?

not sure what you mean by spring top and bottom but they were the same as the old ones I took out apart from the extra 2mm in depth

The OEM seals are double spring. A dust spring on the top side and the oil spring on the underside.

oh I see never too old to learn 🤓
Oddjob:
Ted, the Pyramids seals have just this minute arrived.
The difference in the stated depth is because they state the depth of the body of the seal at 13mm but they also include the depth including the upper lip of the seal, the part that touches the fork stanchion.
They are double lipped but no springs are visible at all, they appear to have sealed the springs inside the seal body, they weigh a lot more than standard seals due to this. I can expose one of the springs if I peel back part of the the rubber seal lip but the upper one is completely enclosed. Small packet of rubber grease included.
They look really good, I'd say go for them.

Advice taken Ken I'll order a set thank Bud.

Just realised I have not updated my 500 project for a while - front forks now re-assembled and back on the bike with new front mudguard etc in place.
Gear shafts in place in the upper engine casing waiting for a pair of Brown mains from DS - Plastigauged existing Big End shells & all good.
Red assembly lube needs cleaning out - it is remnants from when the old crank was in place last year.
Did something to my lower back last week whilst working in the back garden & pond so presently being sensible until my back pain subsides - I'm going to see if I can hang by my arms from the garage loft hatch to help ease the pressure on my back - it used to work when I was younger.
