Previsibles are for select group of collectors. I have a few in my collection but they were not the target of my quest. Will they become collectible I really don't know. If you like them and the cost is not stupid why not.
Jeff, after another look at the pic they seem complete and if the nozzles are correct that is a bonus. And if the hoses are old and in good condition another plus. With that said it might sway me on my buying decision.
