USA made, heavy duty Wayne locking gas cap with two keys in "B" size, which from what I've found will fit a 29-48 Ford, 36-48 Lincoln or 40-48 Mercury. The swiveling lock cover has a neat fin on top. Chrome is ok, no deep pitting but is chipped on the key cover. Cap is 3-1/8" overall diameter and filler section is 1-13/16". Shipping in the U.S. is $8 via USPS Priority Mail.
