After a full restoration, successful mod and cleaning procces of my Hohner Pianet M, it's time for slight sanding and oil/wax finishing before it finds its place in my studio. I also have to recreate the horizontal leg's supporting wood plank as it was damaged (not by me) during transport.
So it would be good to know the kind of wood originally used as much close as possible. Wood is the same across the whole instrument.
In a walk to local old woodworkers, i was told it's probably European oak (Pianet was made in Germany). One of them mentioned teak wood.
I'd like to get your opinions too. Personally i believe it's oak, browny/reddish stained.
* I don't own any of those pics, they came straight from Google.

Can anyone identify?  oak, teak, other?
A possible stain/finishing method guess would be appreciated too.

*** You can definitely feel wood grains by hand touching.

Having had some experience it does look like an oak maybe veneer difficult to say when we don't see the interior. French Oak was and continues to be popular.
Looks like a spray finish. Maybe a cellulose varnish.
Depends when it was built. It needs a suitable construction and water resistant , Has it got a ringer cup marks or plant pot damage? You would see a bloom mark.
Builders would be aware of this prior to finishing.
I wonder if there's any mention in the sales catalogue.
Happy hunting.

Ma throats as dry as an overcooked kipper.


Smoke me a Kipper. I'll be back for breakfast.

Thanks Rich, yeap it looks like oak to me too. It isn't veneer though. According to Wikipedia its approximate manufacturing span was 1977–1983.
I believe it is finished with a kind of oil based wood stain of the era. But I'm probably wrong.
I've also contacted Hohner company, you never know.
You can definitely feel the grains with your hand, its porous kind of relief feel.

An old kind woodworker was willing to help and told me it won't be such a big deal. He offered to give me a spare wood plank left laying around from a previous project he'd done in the past but i have to wait some days cause his lab is like a mess and he wants to find a piece as much close as the original with identical grains. He'll also sand it properly (120/150/220 grit) and then i have to decide which way i should go for finishing.
He told me, if the starting material wood plank is reddish enough, even two or three coats with teak/tung/linseed oil combined with wax could do the trick.

But i believe (specially if the plank piece is the common white oak) that i should go with a brown red wood stain first then finish with oil&wax.

In any case, it should be ideal if anyone experienced out there could guess how they probably did it back in the days.

Just shot a pic.
** Ps. I slightly teak oiled those pieces yesterday that's why you can see some stain drips there. The older brown stains seem like it were there from the beginning so that should be a proof of wood stain dye used.

Looks like oak to me. We have lots of oak furniture.
It's not dog wood.
You can tell that by its bark.

It's chipboard/MDF Oak veneered actually but some small pieces are made by pure oak. I'm wondering why most woodmakers told me it's pure oak across whole instrument. Maybe they consider it as a self evident thing and they were talking on what kind of wood thd veneer is accord to grains who knows  8)

Having broken up a few keyboards in my time the only real solid wood I've found on the exterior is the front cross strip below the keys. Even really old things like harmoniums were veneer over plywood.
Looking at the original flat board stand it looks typical of veneered particle board flatpack furniture design. It has little to resist warping in the structure which would be a danger with solid timber planks. Even in the piano itself, the end grain treatment is unconvincing.
I can get that red tint with a mahogany stain.

Project done. Thanks everyone here.

Deffo Oak. Now't wrong with veneer - it's the quality of the veneer and the carpentry that makes the difference. It is not unusual to have ply panels with oak veneer - much better than chipboard or MDF, so far as longevity is concerned.

Looks nice, by the way!
