Nick, Welcome to the forum. As Eiji has stated the serial number is most likely 83S2866. The number that you supplied is not a valid serial, can you please confirm and I will add it to the title once you have done this. Please be aware that this free service takes time and that Mica completes look-ups in between her many other company duties, therefore we usually have a backlog as you can see from other posts in this section and they are completed on a first come first serve basis. Thanks for your patience. Art
