Piano, Organ, and Keyboard/How to determine the age of a Kimball model #4245


I don't know much about pianos but, want to learn how to play.  In trolling craigslist I found two pianos in decent condition but can't really tell their ages.

Kimball model 4245 - serial number D93838
Gulbranson - 463718

The owner claims they have been recently tuned - and to my untrained ear they sound okay!

Can you please help - any information would go a long way.

Thank you.

Hi Nadia:

The Kimball was made in 1984.

The Gulbranson in 1957

The Kimball 42 inch console is more than likely the better buy.

I always suggest the following just to make sure:

Go to

There you can locate a local registered member of the piano technicians guild.

Tell them what you propose and have them come out to take a look.

Sometimes they will reduce the charge if you promise to use them as your technician.

In any event, there will be no surprises!

With regard to "just recently tuned" ...ask if it was done by a registered member of the guild.

If so...ask for the technician's name. You can use that same locator tool to verify their being a registered member. I you plug in their name and it doesn't some were given bad information.

If you have trouble with the look up, give me the name and I'll help.

Is there one owner of both this a retailer?????
