The replica is almost finished. There is still the pickguard of the original and the pattern on it that I have to imitate.
When looking at the picture of Paul Tutmarc and his instruments:

and at the 736 of Peter Blecha:

and other pictures of Audiovox instruments on the net, you see the pickguard has a silver color.
Let's see if I can turn brass into silver (alchemy?).
I took a zinc-carbon battery apart for the zinc and ZnCl.
I dipped it in vinegar (added salt and sugar) and let it soak for a couple of days.
Then I took a piece of brass, connected it to the minus of a powersupply (5V DC) and put it in the solution.
I hooked a piece of zinc of the battery to the plus of the power supply.
Then switched the powersupply on and let it run for 30 minutes.
What you get is a grey mat layer of zinc on the brass. After polishing, it turns into a shiny silvery layer.
Then with a technique called brush electroplating and some masking tape, I made some patterns on the zinc by adding more zinc.
This is the result:

¡Bravo!
