Is it possible to check if a lever shock is working effectively when it's off the car? If they are the original shocks would it be reasonable to assume that they would be worn out after 50 years and that they should be replaced with rebuilt units? Anyone bought lever shocks from Nosimports on Ebay for $77.00 US with $30.00 refundable core charge?

I'm still driving my TR3A with the original rear lever shocks from new in May, 1958. I restored the TR from 1987 to 1990 and at that time I drained the oil from my shocks and replaced it with genuine Armstrong lever shock oil. Since then I've driven another 113,000 miles with no issues. These shocks have been on my TR for 194,500 miles from new. Why change them. ?
Reminder:- if they are off the car, re-fill with the shocks standing up in the correct vertical position as they would be when mounted on the car. This is to avoid over-filling.
If the lever moves as it should - resistance in one direction and a quick return in the other direction, they are operating as they should.

My take: Change the oil, then mount the shock upright and cycle the lever a few times to work the bubbles out of the cylinders. Double check the oil level and add more if necessary. Then force the arm through a full stroke up and down. You should feel the same resistance throughout each stroke (though not necessarily the same between up and down). If you can feel places where it moves easier or harder, the shock is worn out (or damaged).
As the Moss article notes, this is not a complete test, and certainly not grounds for evaluating performance or comparing one shock to the other. But, if they flunk this simple test, they are definitely bad. And if they pass, they are probably OK, IMO.

That eBay seller I believe is Peter Caldwell at World Wide Auto Parts in Madison, WI. He has been rebuilding them for a long time and I've never heard any complaints about the results. If you poke around on their web site, I think there is even an article on what all they do as part of the rebuild process. The result should be literally "better than new", even if you don't go for the various extra cost options (like increased damping, adjustable damping, etc).

I've got a pair packed up myself to go to him, just haven't sent them off yet. You need to contact him first, to get the instruction form and packing slip. He also offers options like immediately shipping rebuilt units from his stock, or waiting until your units can be rebuilt (for the true purists); and how much paint to apply afterwards (none, primer, arm only, entire shock).
