Attached is a picture of Winston before being stretched and still under the old name "Victoria Regia". Also attached is an IWM picture of an LCG (M) and an LCS (L)....as a Rocket ship. I actually think the LCG (M) and LCS (L) might have used the same hull, but I haven't found any measurements or info to confirm this.
An LCSR survives as a house boat in Stockholm, by the way!
