A rimfire .22 Long Rifle cartridge, HV stands for High Velocity. Early .22 rimfires were black powder- when the load was changed to smokeless powder (which drove the bullet faster) some older guns could not shoot them without failing. The HV designation means they can shoot standrd modern day ammo.
Yes. The original .22 rimfire cartridges were low velocity- black powder. When this changed to smokeless powder, it gave a high velocity (HV) which caused wear and tear on older guns. Guns were marked HV to indicate they could use the new ammo. It should be able to fire standard .22 Long Rifle cartridges. I would not shoot hypervelocity ammo such as Stingers or Yellow Jackets in an older gun.
You will have to check the auction sites.

The Elmo HV series are simple to use, but calibrating can be difficult.
He is now 30 years old , I couldn't know when he was born exactly but , now he is 30 years old , born in 1981 , in portland ..... hv a nice day :-) Ryan
insulation tester (Megger) can used to checked the short circuit on HV side. HI POT tester is also a means to checked the shot circuit in HV cable.
The Elmo HV series are great for presentations and have very strong colors.
in hv side, current will be less; so if we vary the rheostate, than thetre is less arcing with respect to lv side, so we always put the tap changer in hv side.
