I'm looking at the Sapherson booklet and the Hall prints. In Sapherson he lists two Guard cavalry regiments - Livgarden til Hest (in a red or yellow coat depending on who you believe) and the Livregiment til Hast (in a grey coat). The Hall print show the R.R. Livregiment in a red coat.
So my question is, which one is right? Which one has the red coat?
