121 var (198s) 1917 1½d bistre-brown K George V Admiral, overprinted "SPECIMEN", (Samuel type W3), this is by far the rarest of the Admiral "Specimens" as it was issued 4 years after the set and is often missing from otherwise complete sets, almost impossible to find as a single, brownish OG LH, (the famous Gibbs set contains a no gum copy), rare!, toned.
