Sorry, that's just a hand crank phone. No dials, no phone numbers. Cranking would connect to an operator and you would ask to be connected to a certain person. The operator may have asked, "What party are you trying to reach?" But it didn't mean party line, although in the early 1900s, there
were many party lines due to low supply of copper wire during the wars. A party line was a looped line connected to two or more phones in close proximity, to save on copper. But mostly it was the operator using a switchboard to connect you to the desired receiving phone. Back then, operators had to know what they were doing. In larger communities, they had "exchanges", which were groups of connections in certain areas, and you could tell where in a neighborhood the phone was by the first two letters. Look at photos of switchboards...there were complex.
Teenagers today probably wouldn't know what to do with a rotary dial phone, let alone a hand crank phone!
I remember when we only had to dial 5 digits, then it changed to 7 digits. Eventually changed to 10 digits, prefixed by "1" even for going to a city/town that was outside the local exchange. These days, dialing "1" isn't required on IP land lines.
