The underside seems to always have the factory mark of E, W, or R. I have an Eddystone
bolt with NO ordnance stamp, only the "E" under the handle. The stamp is "proud" and doesn't
look to be refinished. The top part of the handle is smooth with no stampings. Because of the
"E" stamp, the bolt was made by Eddystone. The references don't address this issue. Any ideas?
