Fan for an old Linde AC 295 amp welder

[BWS29128]

Not sure how far you'd get calling them, but Linde welders are now ESAB.

I am looking for a fan for a very old linde 295 amp AC welder. A friend of mine found one very cheap at a public auction. He brought it over to my house to try and it welds very good. The fan is the only bad component. He would appreciate any help to locate a fan.

Thank you
