This one fell from the third floor I guess, oh my...  The corner was filled with body panel putty, we'll see if we can save it.

This is another reason why I bought the M70's, the optional trumpet stands!  Agreed they need little care to get rid of the corrosion. 

Front grills completely destroyed... 🙁

Lets start!

Both speakers were completely dismantled for an entire restoration, I mean from A to Z.  First let's take care of that corner.  Once the putty was removed, luckily the rosewood veneer was still there but the corner was severely damaged. 

With a precision knife, the veneer was separated from the wood.  This revealed that the corner was in terrible shape and only a whole reconstruction would make it right.

Many Many hours later with a lot of TLC, the original veneer was put back and finished the best I could.

Both cabinets gently sanded and polished with 0000 steel wool

The final touch, 3 coats of satin varnish... 

Let's take care of the drivers now.  The original SEAS woofer in the M70's suffer from badly assembled terminals on the speaker housing.  The terminals come lose and the spacers are rattling against the cone.  Eventually, the leads are breaking leading to speaker failure.  I was lucky to have all good drivers requiring little repairs.
