Other countries must contact me for a postage quote. Please look at my other auctions and put me on YOUR FAVORITES. Most items are sold "AS IS" with a "no return policy" unless stated otherwise in the body of the ad. I have always treated my customers with the utmost respect and will answer all emails to the best of my ability. I am not an expert concerning much of what I sell but I do have a certain amount of "resourcefulness". Please send part numbers when inquiring about certain parts. As time goes by I am amassing a data base concerning many of these products but most of what I sell has been in storage for years and that information can be hard to come by. An educated buyer is my best customer. Any help from you folks will be remembered and rewarded when it comes time to "wheel and deal". Thank you. Mike
