Is there a difference between an army mount pipe and a spigot?

[Haebar]

I believe that a spigot is the name for a military fitting where the tenon is clad with metal, usually silver. They usually have a matching silver band.

This from the Peterson's web site:

The Peterson tradition has long been associated with the fine sterling silver detail of our pipes. The Peterson Spigot is characterised by a sterling silver covering on the tapered end of the mouthpiece which compliments the sterling silver band of the pipe. The Spigot style evolved from the practice of soldiers in earlier centuries who repaired broken pipes by sliding a used cartridge case over the shank and reinserting the mouthpiece. In this unique spigot finished pipe, Peterson craftsmanship perfect the union of finest quality briar and precious metals. The silver is spun to shape and then fitted to the pipe. The craftsmanship, created with only a lathe and chisel as basic tools, is the finest in the industry. Normally fitted with fishtail mouthpiece. Peterson lip is available made to order.

I had a GBD spigot pipe at one time and it was a military fitting.
