Beautiful restoration. Lucky you've got a number card holder; that type is getting hard to find.

Yeah, that will work! Nice!

Thanks.

I'd include the model #.  It's not a common phone so few who see it and are interested are likely to know it.

That's a great idea.

Thanks, I'm just finding that out.

Well, I think I figured it out. I copied the card picture to Microsoft Word, then I resized it with word. I printed it off and it fit. It's about as good as it will get with my lack of talent for resizing pictures. :) The number holder size is 1 3/16th.

Some pictures taken today outside in natural light on the tonneau cover of my pick up. With the dial card installed.

The microphone that I bought off eBay arrived this morning, all wrapped up in eBay tape.
It is in better shape then I thought it would be. It even has the right adapter for the phone and the colour matches.
That will be todays project to clean it up and see if it works. Then I will try and make the logo's for it.

The microphone that I bought off eBay arrived this morning . . .    It is in better shape then I thought it would be. It even has the right adapter for the phone and the colour matches.

That's fantastic, right color and connector. eBay is funny that way, what you get has a 60/40 chance of being much better or much worse that pictured. With the quality of images posted on eBay these days, most stuff turns out better.

Hope it works and can't wait to see your finished project. That will be something few others have in their collections.

OK, I jumped the gun here a little bit. When I opened the package this morning I seen it was gray and thought a perfect match, next was the screw on female adapter type great 2 for 2. The phone was in the garage and I was in the house. When I got around the morning on checking it out, I found that the gray was a little lighter on the mic, I can live with that. But the female adapter was larger than the male one on the phone. Now I'm going to have to find myself a female smaller adapter and swap it out.

I gave the mic a good cleaning this morning.

Yes, the mic connector looked a bit large but when not next to the phone, hard to tell. At first I thought the phone jack was a female BNC but then the threads were apparent. Maybe DavePEI could find or knows of an adapter to convert the large male to the smaller jack. Radio seems to have any and all types of adapters which could avoid cutting off the original plug.

The mike connector on the mike cord and the one on the chassis are standard and miniature versions of a common connector used for high impedance mikes on consumer electronics.  I think they were made by Amphenol but might be Switchcraft or possibly both.  Are there any markings on the plug?

I've seen lots of audio adapters but don't recall ever seeing one for a large mike connector to a small mike input. 

An adapter would make the large long connector on the cord stick out much more than a smaller replacement.  A large diameter long connector adapted to a smaller stationary chassis connector would be particularly susceptible to breakage and clumsy looking.  Therefore I'd recommend replacing the one on the cord with the miniature version even if an adapter can be found.

Here is the full size Switchcraft version of the cord female connector:

http://www.switchcraft.com/Specification.aspx?Parent=810

This shows both versions:

Here is the miniature version:

Thanks Alex,

I ordered a new female adapter in the right size (mini) from Digi-Key today. I'll replace the larger one and keep my fingers crossed that everything works out. :)

You're welcome Doug.

I'd forgotten about the rationale for these connectors but looking at the web pages reminded me.  These are what might be called a "hermaphroditic" connector (not my choice of terms) because a female can be connected to another female by sliding the ring back on one of them, effectively making it a male.  This can be convenient when working with long extension cables.

Paul F. doesn't know it yet, but his picture he posted helped me with an idea.

This is only a test to see if it would work, I think I can get them made out of vinyl.
