This is a battery rest that will never really need upgrading, its EIN [020] in Aqua and the only thing I can find wrong is at a mold line on the rim is a wee burst flea bubble or possibly a teeny chip. There is a neat bubble by the S in the embossing plus at least 5 bubbles in the crown the part that sticks up. $50.00 U.S. plus shipping. I accept PayPal in family/friends mode also cheques. First email as usual.
