Which older pianos had plastic parts?

I know that some of the pianos manufactured in the 40's and 50's had plastic action parts that did not stand up well. Is there somewhere that lists which companies used these plastic parts and on which of their lines of pianos?

Unless you are going to be buying a 40-50 year old piano I would not be concerned with this. Plastic or should I say "high end composites" are now being used by a number of high quality piano manufactures.

It is analogous to automobiles, there was lot of junk plastic in cars just 20 years ago but things are different now.

There is no definitive list. Some actions used plastic parts some of the time in some pianos, but not all of them. It changed from time to time, depending on what was available.

Thanks for your response. I was afraid there was not a definitive list. A family I know is looking for a piano on very limited budget (thus, 40-50 years old is probably what they will find). I was hoping there was a list so I could warn them against those specific ones. I know that the best way is to have a technician look them over, but I'm not sure they will spend the money to do so. There is an Acrosonic available from the late 50's that I thought might be worth a look for them. I know Acrosonics were generally well made. Do you think they are likely to have any plastic in them?

Acrosonic did not use plastic, as far as I know.

I agree with BDB. Baldwin didn't use any plastics in that era. The Acrosonic is a rugged work horse which has stood the test of time. Suggest that they have an inspection by a piano technician and they might have found a very decent and useable piano.

Gulbransen's and Whitney's are two in my memory. but pretty much only in the spinets are they a big problem.
The elbow at the bottom of the lift rod for each key had a plastic elbow that disentigrates very easily, and is expensive to replace. My best advice is stay away from spinets.
Good luck to your friend.

Lester, Fischer, and Sohmer are some that used plastic parts in that time period.

Mehlin, Winter and Janssen for plastic elbows and (sometimes)jacks. Many, many more manufacturers used plastic for damper flanges.
