Wonderful! This is very exciting. Thank you so much for the photos. Do post more when you have them.

I see your restorer is fitting Abel hammers.

It would be very helpful to me if you could tell me the serial number of the piano!

Just curious: The strike line of the new hammers in the treble section looks completely straight. For a piano this age one would expect that the optimal strike now resembles a slight curve. Wouldn't it have made sense to wait with fixating the hammers until the treble is restrung, then finding the best possible strike line and only then glue the hammers to the shanks in this defined position?

My 1886 Steinway deviates from the straight line up to 4.5mm - and soundwise it made a huge difference to remove 42 hammerheads altogether and glue them back into their place.

Still, very nice to see the care that is taken by the restorer. Seems like the pin block is still very good and that you will keep the old pins. Will you keep the agraffes?

Beautiful looking instrument ! Best wishes on the restoration of this instrument. Talking about the hammers I am quite excited I was able to recognize those hammers as being Abel
even before I saw the usual brand mark on the side .The trouble is I have no idea how I recognised them as being Abel except that I am always looking at Renner and Abel hammers ,trying to find out if they look different ,apart from the colours.

Actually it looks like the serial number survives!

In the photo of the soundboard you can see where the transfer once was, and it looks like the remains of the number '29734' are there, which if that is correct, puts the piano into the mid-1880 or thereabouts, and that looks consistent with the design of the piano.

Joseph, that is exceedingly observant of you. Well spotted! I don't know how I missed that. Unfortunately the resolution of the photograph is not really good enough to tell us the number with any certainty.

This was a period with rapid evolution in Bluthner design. In my database of over 1300 pre-war Bluthner grands, I only have records of two instruments of this style. These have serial numbers #22771 and #23852. My records are sufficiently comprehensive that it seems unlikely that the serial number of Pierluigi's piano would be very different from these.

According to the Bluthner date table these two serial numbers give a date of 1883/4. Or possibly, with the 3-year correction that is indicated by my own piano, the date might be 1886/7.

Pierluigi, because this is such a rare style, it would be really helpful to me if you could take a good look at the soundboard and see if you can read the number more definitely. You may also be able to find the number pencilled on the rear of the music desk, and on a paper label at the rear of the action cavity, on the right-hand side. Also, you may find the number on the rear of the keyslip and the cheek blocks.

It is a fine project to restore a musical life to this noble looking piano. Among piano cognoscienti, Blüthner is a revered make, admired for its sweet, singing tone. On the underside of this piano I was amazed at the number of beams supporting the frame of this instrument. It should be a very stable piano when finished. I hope that the completed re-build will delight both your ear and eye.
Kind regards,
Robert.

The other place where Blüthner puts serial numbers is on a label at the back of the action cavity on the treble end.

I'm surprised your restorer says he didn't find anything, because, as Joe points out, there is a clear remnant of what appears to be a serial number. Well, before he sanded it away.

It appears he is re-notching the bridge, but the bridge (or is it capped? hard to tell) clearly has splits. Wouldn't it be better to completely replace the bridges?

Not only that, the serial number is right where I said it would be, in very big numbers!

Interesting, the soundboard looks to be in very good condition even before the shimming, and that seems to be a replacement pin block anyway - was that installed by your restorer or was it already there?

It's also interesting that it's not the patent action. The action in the piano is almost certainly the original one for the piano and not a later replacement.

I still don't see anything about the numbers.
the mechanics do not know if it has been modified over time or if it is its original one.
the pinblock was already there, it was not replaced.
actually i am not doing a full restoration. so based on the money I'm spending not everything can be done perfectly.
6.000 $ is my budget.
