It can be easy. If air readily escapes when you open the valve, it's probably not clogged. But if not, and it remains pressurized, you do not want to try taking the valve off.
After letting all the air out, the valve should unscrew without too much effort, if they had proper o-ring and lube separating the dissimilar metals of the cylinder and valve.

As said an early LP 72 made by Norris. It had a working pressure 2250 psi but only a full 72 cu ft with the 10% (notice the plus beside the data of 60 or perhaps 69?). So when filled to 2475 psi it will have 72 cu ft.
Now the valve is an old ScubaPro valve with a built in fill indicator. Notice the F 1/2 E marks. BITD divers did not have an SPG so everyone had a gauge but only for topside usage. The fill gauge on the valve was an alternative.

Take it to a shop that actually does the hydro on sight, they can take a look and let you know if needs a tumble, if the valve needs work and anything else. They should be able to tell pretty quick if it can be but into service and how much and then you can decide if its worth it. I picked up a steel 72 that was manufactured in 1976 and sat around for about 15 years unused. It needed a tumble, I use it all the time now.
Date to me looks like 1969...I have one just like it..Tank has a Scubapro DCAR valve on it--depth compensating adjustable reserve..if it passes hydro its a good tank.very comfortable to use and I actually prefer it over todays alum 80 cu' tanks. I have a couple that live on my boat. As to the epoxy covering, it really is not an issue with this tank. The tank is galvanized and has the coating on it. You can see it is galvanized by the bare steel showing on the hydro stamp, it is not rusted.

Please do not take it to your local dive shop, take it to a dot certified hydro tester and be sure they are aware of the special procedure required to hydro a galvanized tank. The two links are from PST and Worthington but applies to all manufactures of hot dipped galvanized tanks. You have a great tank, be sure it isn't ruined by ignorance.
Find a hydro tester near you here.

Procedure for testing galvanized ta ks, I suggest you make copies and bring them with you to the tester.
