Certain Regiments in the Imperial Army, were given the right to wear horse hair parade plumes. Recently I had to do some solder repairs to the OR's parade trichter which came with James' Garde Dragoner SOS helmet. Before sending it back after restoration, I took some pictures as I don't believe we have discussed these before. Anyone with an officer example, please add some photos to this post. Anyone with a Bavarian or Hessen example please do the same so we can see the differences.
There are 3 parts to the trichter, the column, circular top and horse hair parade plume. James kept the plume as I did not need it, I am sure he will post pictures once he sees this thread. The horse hair plume comes in 3 colours, white, black and red. A red plume was always worn by musicians. I do not know how a "plume colour" was assigned by the High Command. Garde Regts. wore both black and white. Trichters come in brass and neusilber white metal, they match the fittings on the helmet.
The top of the column, there is a soldered nut on the inside of the brass disc which can not be seen here. The threaded rod soldered to the brass top screws into this nut. In this case, the nut had come unsoldered and was bouncing around inside the column. I had to unsolder the disc, resolder the nut and then resolder the disc. The brass top is screwed down and sandwiches the plume onto the column.
The screw post which holds the column onto the spike neck. The small brass disc has holes in it to release hot air during the soldering process.
