I have recently bought a Columbia 160 portable that has a missing latch on the records compartment lid. That is: it's not one of the "main" latches on the front of the case, but one of those belonging to the records compartment on the top half.
Unfortunately the surviving latch shows that the missing part has a distinctive design which is not easily mocked with nowadays hardware.
I figure that an original spare will be nearly impossible to find. However, should anyone of you have a spare latch or knows someone who sells them (original or reproduced, I'll take everything!) please be so kind to let me know.
Also, should anyone know the art of reproducing such part from raw copper, I would be very glad to purchase an imitation latch. Please let me know who may be able to do the work, or contact me directly.
In any case, what would you personally do if this gramophone was yours and this part was missing?

Making a replica latch for a Columbia 160.
Due to the lack of hints, and also to the lack of for sale offers, I boldly decided to try and make one myself. Not without my surprise, the replica latch came out quite nicely, I dare to say. Here are some pictures that I took while making it; perhaps they will be of inspiration to someone else.

- The original latch is all made in copper. Although I searched high and low, I could not track a copper sheet of the appropriate thickness. However, a brass sheet of quite the correct thickness was available. I decided to go with it as it is almost just as well malleable, and brass and copper can be anyway welded with a tin solder (more on this later).

- This is a key-point: how to make the hinge. The hinge on the original lever is made of folded metal; it's very narrow and it seems impossible to re-create it with household tools (at least to my eyes and with my tools). I then figured that soldering a small pipe at the top of the lever might work. The pipe is made with a short piece of copper pipe used in refrigerator compressors. Unfortunately the pipe has proven not to be ready-to-go: when I cut it accurately I realized that the inner gauge is extremely narrow, so the hole had to be enlarged with a microdrill anyway. It takes patience and a very steady hand.

- The bored pipe is welded to the lever of the latch. This step requires precise positioning, for the latch to operate efficiently. The pipe has been soldered, desoldered and repositioned many times by trial & error before the correct position had been find. The toothpicks prevent the melted tin to enter into the side holes and fill them, and they also help handling and keeping the pipe in position.

Marco, you really should move to the U.S. because you've got the "Yankee Ingenuity" down!
Very nice job!
