QUESTION: I have a cable Nelson upright piano serial number 86846. I would like to know what year it was made and type of hammers on it as some are broken

ANSWER: Hi Cecilia:

Your piano was made in 1914.

I'll assume that it is a large upright.

The hammers are typical, and most likely it's the hammer shank broken and not the hammer itself.

This is entirely repairable.

If you go to http://www.ptg.org, you will have the opportunity to plug in your zip code and get a list of registered technicians in your area. They will be able to fix the problem.

If you need anything else, don't hesitate to get back to me.

QUESTION: I am very curious as to whether the hammers are typ A or type B. it would settle a debate?  Thanks

ANSWER: Ooooooooopppppppppppps.

I think I got this twice.

Did you see my second response.

Further, most piano technicians come prepared to fix such issues.

Just make sure the technician is registered...you will be better off for it.

QUESTION: Do you know if the keys are made with real ivory or is it something else?

Hi Cecelia:

Unless the keys were recovered, they were ivory.

How to tell:

Ivory keys have a "bone" grain pattern to them

Ivory keys are put on in three sections: The front piece, the head (where your fingers generally touch the key) and the  tail (the part that is between the sharp keys).

There is a definite seam between the head and tail piece.
