I had the pleasure of attending the "Silent Movies in the Park" event at Two Strike Park in La Crescenta. This was a live performance of multiple films on a hybrid Magic Lantern and silent movie projector rig. The performance was facilitated by Joe Rinuado through his involvement with the Historical Society of the Crescenta Valley. Joe brought along his 1909 Power's Hand Crank motion picture machine with a Magic Lantern sliding attachment to project vintage 35mm films and Magic Lantern slides.
The projector appeared to be a wonderful piece of machinery and a bit of an engineering marvel.
Joe carefully, and patiently prepared the machine for the show.
The film reels were brilliant and beautiful.
The metal lighting box was typical of a Magic Lantern of the time but was on rails so it could slide in between the movie projector and the Magic Lantern projector.
Underneath the illuminate housing was a voltage control for the 82V needed for the projection bulb.
Cliff Retallick was ready to accompany the show on the Piano!
The show started with some fun Magic Lantern slides.
The hand cranked reels lasted for about 20 minutes. Joe took turns with his assistant Gary Gibson manually cranking the projector. You could tell it was a pretty good workout!
Joe would then need to change out the reel. When this happened, he had the ability to slide away the movie projector and Gary would slide the Magic Lantern into service. It was a great setup!
I was contacted by a coworker who was retiring. He was moving out of state and had an old radio in storage. He asked if I was interested in taking it. I went and picked it up from him in a storage facility. The radio was certainly showing it's age.
The radio is likely from 1946. A wonderful piece of audio equipment from the post WW2 era of Andrew's Sisters and Bing Crosby! - "war production brought new electronic developments".
This had been a family radio for multiple generations, likely purchased in the Los Angeles area in the 1940's. As I had worked with this person for several years, I wanted to give it an extra special restoration. It's not often that I know the pedigree of a radio that restore and I like to think of myself as a steward of the object preserving it for the future. Here's a photo of the radio in their home in 1956. It would have been roughly 10 years old at this point.

Initial Triage
I brought the radio up slow on the Variac. Surprisingly, it was in pretty good shape electronically. The turntable did not move, but I was able to get the radio to play. Other than the turntable, some missing dial lights, a large hole in the speaker, and dirty switches it appeared to be electronically OK.
As the radio was playing, I decided to pivot over to cosmetic restoration as the first priority.
Cabinet
Overall, the cabinet was not in bad shape. Rather than do an refinish, I simply touched it up with Howard Restore A Finish. It's a great product, and I've used it on multiple projects.
Grille Cloth
There are multiple places to get grille cloth, but I like Michael's products at RadioGrilleCloth.com because they are reproductions of original cloth and he lists the original source. Although he didn't have an exact match, I ordered several choices. Top to bottom are his products #01, #17, #11A, and #02A.
I held them up one by one to the radio and ended up going with their #02A. I felt it looked best next to the dark wood.
The Grille cloth was cut to the original backing board and then attached using 3M 77 Spray Adhesive.
We then we used a small torch to melt the polyester threads to keep them from fraying. You have to be careful with this step. Don't get the flame to close! Best to practice first on scrap piece of cloth.
Handles
I tried cleaning up the original handles. Unfortunately, they were brass plated over steel and the iron had rusted which meant they were not going to clean up. Trying to remove the rust was going to take what little brass plating that was left along with it.
I ended up picking up replacements from Van Dyke's Restorers. Fortunately, the "Colonial Revival" style was pretty popular in the mid-20th century and still is popular today so I was able to find a suitable replacement.
With the cabinet cleaned up, new Grille Cloth installed, and the new handles in place, the cabinet was starting to look pretty good!
Electrical
Unfortunately, I didn't get completely let off the hook on electrical and mechanical repairs. The speaker and turntable needed some attention.
Speaker
There was a hole in the grille cloth that went all the way through the speaker. Fortunately, the piece of broken away speaker was still sitting inside. However, the paper was VERY brittle. Rather than sourcing a new speaker, I decided to repair the old one. I did my usual trick of putting some rubber cement on the broken seams to hold the pieces in place. There was still one small hole, but this did not effect sound quality.
Turntable
The turntable is a Webcor VHF Diskchanger model 1841. I pulled the turntable out and tested it on the workbench. Operation was rough. The turntable was dry and rusty inside. I carefully went and lubricated the moving parts with Lithium Grease.
Once things were lubricated up, everything started popping back into working order. I went through all the automatic operations and record changing.
Here's a short video of it operating
With this fixed, all that was left was to replace a few dial lamps. Most radios of this era take a #47 6V dial lamp and I keep those in stock so I was able to replace the missing ones.
This got the whole combination up and working wonderfully!

The radio came with the original manual for the turntable. Sharing here for anyone that might need it for their own project.
