Can I use and old pianos strings for another piano that’s missing some?

I have a 1942-1947 Wurlitzer upright piano and it has a few broken strings and I have another Piano from 1952-1953 Cable upright piano that I got for free and all the strings are perfect and in tact can I use the strings on that one for my Wurlitzer piano or will I have to buy the missing strings brand new?
