Old Nitro Duck tank - info and how much is it worth?

[Blake_sw]

I acquired a 68/45 adjustable tank in a sale awhile ago and I'm looking to sell it. Only thing is I don't know much to sell it for.

It's pretty old, hydro date is 6/98, but it's recently been rehydro'd. Adjustable from 0-1200psi. I couldn't find any pictures of it, and it's not an old Nitroduck SS4500.
Any help would be appreciated. I was thinking of selling it for a price between $140-160.

a bit over or less than $150 should be about how much youll get for it, its adjustable and its got a new hydro, so i dont think theres anything wrong with it
