I have finally found a picture of a wheeled EOD shield from 1971 – courtesy of RLC Museum. Compare these two largely similar tools, the first from 1573, and the second from 1971 – 402 years apart. I believe the shield was used operationally in Hong Kong in the sixties, and quickly went out of service after limited use in Ulster in the early seventies.
circa 1573
circa 1971
