After a short period of not selling many restored ECOs, we recently have be almost overcome with requests to purchased our restored meters. While we have enough to take care of the orders we have we need to purchase a few ECO mechanisms. We don't care about the condition of the outside of the meter, we are in need of the mechanism that are on the inside of the meter. If you have any for sale. let us know. Please email us at
