It's probably the type of lubrication they used, and lack of use may make things worse.
I just had to have a 1961 Rolleiflex serviced I knew the original owner well - he'd only put a few, he said 6, films through it, he also had a Yashica which he used in preference, he wanted to "save" the Rollei.
Lack or little use can be a bad thing in some ways, also lubricants and the materials used to build lesnses change.
