Blow moulding clear plastic

Funniest looking “stone” I’ve ever seen, but as I haven’t passed by it for a couple of years, I’ll put it down to old age and forgetfulness.

The Seahawk on duty Dec 2020

The Sea Hawk on the gate at Culdrose (HMS Seahawk) is mounted on a low stone structure.

That’s appears low from the car when driving past. I don’t know how low it is if you’re standing next to it.

There is a Seahawk on the gate at NNAS Culdrose, Cornwall, perhaps they might allow you to make a clay impression of one on that A/C?

Aero modellers used to do small plastic canopies for they models. Perhaps once you have a suitable male or female mould their techniques could help.

Alternatively, why not carve one, paint it and use that.

The originals were quite thick – 1/8” or more. 

Cant be many Sea hawks to take molds off nowadays
