Osterizer Blender Blades

[charles]

As I stated in an earlier post I recently purchased an older model Osetrizer blender from the early 1970s. The blender only has 375 watts which is considerably small compared to many of the other blenders on the market. I primarily use this blender to make smoothies, margaritas, and slushies. Being 40+ years old the blades are quite dull and I was wondering what type of blades I should replace them with. Also, the blender gives off an ozone smell. Is this normal? the brushes looked used but not terribly warn could this smell be due to another problem?

You can still get original equipment oster blades on Amazon. I bought two sets with rubber seals for $8.
The blades are the same for all models from what I understand.
