Original Bob Ratcliffe Rat Hat Diving Helmet

Item Details

Description

We are proud to be offering one of the most iconic diving helmets of the late 20th Century ever made, the Bob Ratcliffe Rat Hat. This helmet belonged to a Oceaneering employee and former US Navy Seal who passed away in 2020. Included with the helmet is a professional photo that hung in his office of the same or similar Rat Hat.

This original unrestored example has certainly been down on a few jobs. As can be seen in the photos the helmet has all the telltale signs of being used, but not abused. Yellow fiberglass body has typical scuffs and scratches, but none are severe. An original size medium blue head liner is included which is in good condition with some staining from age. The top handle does have the helmets serial number. Please review all the photos for more detailed information.

All diving helmets in this auction will be accompanied by a certificate of authenticity from Nations Attic. The certificate will have a unique number that will match the number on a tamperproof hologram decal placed inside the helmet. This information will be kept on permanent file at Nations Attic and help ensure the provenance of the helmet and authenticity.

All items will be shipped with a signature required upon delivery and full insurance either via FedEx or the USPS Priority Mail. Worldwide shipping available. A shipping quote prior to the auction can be provided by emailing your postal code.
