JC49,
I think you will get a lot of satisfaction rebuilding the radio yourself. We can help you out with problems and questions that arise.
here are some answers to your questions:
1) The truck suppliers sell a manual that includes all the data and instructions for your radio. If you care not to purchase it I can send you copies of another published manual.
2) Normally it is almost impossible to find a new transformer. You should show me a photo of the water damage. Normally the transformers are quite hearty and there are some tests you can do to see if there are shorts.
3) When I convert it to 12 volts I install a transformer from a 12 volt Buick radio around the 1955 vintage. Personally I like to leave them 6 volts as original.
4) I use epoxy glue to replace the pointer. If you have a parts radio you can just snip the pointer off at the bend and glue it on to your radio. You may be able to find a suitable piece of plastic from somewhere that will work as a pointer. The entire arm is unique to that radio so finding a donor with a complete arm is really not an option.
5) I have used a battery charger that will supply up to around 6 to 8 amps at 6 volts. That is what I refer to as a trickle charger.
Feel free to ask as many questions as you want to.
Fred
