A lot depends on how old the HC is. If it is pre-1928 (under about 80,000) and does NOT have the front F and high C# adjuster, then the typewriter is the best choice as it has both. I have never seen a Martin HC with a solid silver neck, only plated.

As I mentioned a few months ago, the C# lever CAN be added to the LH stack bar. On a HC, the adjuster really makes a big difference. The sure way to check to see if it is solid silver is to look around where the solders are and see if you see the solder. On a plated horn the solder will be plated over. Now the exception would be a solid tube that also was plated. You can file metal away and see what is underneath.
