I am in martinsville virginia. However I have been made aware that these are slightly different than some other cartridges. They have wider necks on them I believe. I had a buyer ruin his tap trying to use it while another had no trouble using it so im not sure exactly what happened. I am not going to sell anymore until I found out what they are exactly and what particular machines they fit. They were designed for the coors light home draft machines but I guess they dont manufacture them anymore or something.
