Powerbilt Thoroughbred

I was wondering if anyone I can help me identify shafts, in a set of 1,3,5 Powerbilt Thoroughbred Persimmons, I’ve bought on ebay. Pretty clean and underplayed. I’m trying to identify the shaft that they have, they’re labelled, Thoroughbred LVW5C and have the Truetemper logo on the bottom near the binding.
Any info on these clubs would be greatly appreciated folks.
