Help needed to fix my parents' fan!

[frogcrazy]

Hi, my parents are 97 and 98 and still live in their home. Recently an arm blade broke on the ceiling fan in their room. The fan says Alaska (Sheng Yuan) and was probably purchased 25 years ago. Other information on the well-hidden label is:
E68726 Model AC-4142
Mfr 5AO O100
Where can I find replacement arms? The ones on the fan are bright brass but I could paint them white if needed.

You won't find the exact blade arms that the fan came with, but generic 42" blade arms from Home Depot or Lowe's (sold in sets of 5, but you can use 4 and have a spare) will fit onto the current blades.
