THE STINGRAY B1 BATHYSPHERE

I don't recall this B1 sub from the Stingray episode The Golden Sea in 1965, but then again I was only 4.

I do like the look of it. Do you? I understand that there are loads of different subs in Stingray.

Kit detective Marc Frattassio described the B1 as an underwater gold mining bathyscaph 12 inch model and was built from balsa wood with kit parts and plastic or metal tubing details [TV21 website]

At first glance it reminded me of the unlicenced SHADO Sky 8 sub toy from Japan, but on inspection not really.

B1 does remind me of DIVER 1 from the Project SWORD Annual a few years later.

I wonder if the B1 prop survived the ravages of time?
