bib

I just a got a washing machine. Of course I want to see it work in my unit and I keep coming across a problem. Water is leaking from the hose at the connecting part to valve only on the cold water side. On the hotside it works fine. I replaced that hose on the cold side with a SS braided hose...

Have to replace a 50 yr old backyard bib and dont know if it screws out of the faucet was originally soldered on the the 1/2 " tube What is the best way to approach this ? Below is pic of exterior view. The inside view is just the tube going into a wood sill board. I haven't done any soldering...
