Square tube action rails for Steinway M

...which is why Falcone was in the process of migrating to mounting flanges on a flat surface (vs. the Stwy "cloverleaf").

It looks like a repair to me, quite neatly done.  What would be the 
point of replacing it? 
 

I thought you were referring to the hammer rail or lever rail, and 
yes, I've seen that too because I did it myself, but not with brass. 
I used a square steel tube and inserted a tight-fitting walnut dowel. 
I then drilled 6mm holes right through and from the underneath 
pressed in special threaded plugs, whose technical name I can't 
remember, which have a collar at the bottom and take an M4 screw. 
The hammers are then screwed on using cap-head stainless steel 
screws.  In my opinion the original Steinway tube is a ridiculous 
design.
