Tricky one to work out - these subs ran very low in the water, and it seems almost sacrilege to cut off 75% of the hull, to get it to a 'waterline' stage, and it's still riding a bit too high! The figures are 1/144 ( 1/150 ) railway passengers, with a slice of plastic rod on their heads as caps, and suitably painted. These things had a crew of 8, so the majority are on the casing ( fresh air! ).
The original Holland I was built in 1901, the first submarine for the Royal Navy. She was lost in 1913, whilst being towed away for scrap. She was located & salvaged in 1982 & is now on display at the RN Submarine Museum in Gosport, Hampshire, UK
