I have an original Seeburg M100B or BL service manual dated 1955 from the Seeburg corporate library in Chicago Ill. It is a reprint as the original was a loose leaf and this was printed in 1955 and bound for the Seeburg Library in 1955. There is a letter inside the manual stating this information and on another page there is a sticker saying it is from the J.P. Seeburg Corp Technical Library. Its a really cool manual in really good condition for its age. It is a little stained and has some discoloration but it is completely intact and reads well. It is on Ebay starting at $29.00 no reserve. The link is
