The Crosby Garrett Helmet

In October Christie's (London) will be offering a Roman parade helmet reported to have been found at Crosby Garrett in Cumbria (7 October 2010, lot 176). The helmet is said to have been found in May 2010 by a metal-detectorist, and details appear on the website of the Portable Antiquities Scheme. The fragmentary ("found in 33 fragments, with 34 smaller fragments found in association") Roman helmet was discovered in May.

I suspect there would be export restrictions on the piece if the successful bidder wanted to take this unusual piece abroad.
