I found this pair about a year ago and drove from Chicago to OKC to pick them up. After getting side tracked on a lot of other projects I have finally completed the restoration. I have a noisy pot on one side but will get it cleaned and re-install the foil cal and they'll be complete.
Like others I have restored this pair too had smashed in corners, gouges in the veneer and stains everywhere on the finish. The removable bases were destroyed. I had all of the woofers serviced but since there are no 2230A white cones on the planet I had to leave them and just clean them up. They now look pretty fresh and near new. I'll likely upgrade the caps in the 3107's but will otherwise leave this pair as original as I can.
I would appreciate hearing from anyone out there who owns or knows of any other early pair of 4350's. This pair was likely from the first few weeks of production in late 1973.
