Crossfire 45/4500 & Crossfire 68/4500

Got these tanks in deals from other members and do not need them.
First is a 45/4500 that has a Crossfire reg on it. Needs hydro and has some marks from removing reg. $45 shipped.
Second is a 68/4500 with Crossfire reg that was recently retested. $75 shipped.
I have not tested either bottle.
Paypal is good.
