Question regarding old radios (SCR 300, SCR 536, or PRC 10)

So, I am planning on getting into amateur radio stuff and since I am a history buff, I am wanting to get original WW2/Vietnam radio sets (either working or restoring non working models). I looked it up and I think I would need a technicians license, but would like to aske here just in case. For example, would I need a Level 1 technicians license to use (for reenacting) a SCR 300 or PRC 10 (WW2 and Vietnam era backpack radios)

These are the frequencies these operate on -

for PRC 10: 38.0 to 54.9 MHz VHF 

for SCR 300: 40.0 to 48.0 MHz

For SCR 536: 3.5 and 6.0 MHz

Beyond getting 2 working units, do I need a license to use them?

This would not be a project of building modern ones, but getting original units.
