You are bidding on a factory owner's manual/handbook for the 1970 TRIUMPH Unit Construction 500cc (30cid) Twins motorcycle.  It contains 40 pages.  It's hard to beat the factory manual for comprehensive content.  These manuals pay for themselves the first time they are used and are a must for the do-it-yourselfer!  These are filled with pictures, diagrams, and how-to information.  Just what your glovebox needs!  Manual does have wear/soiling from use and the cover is partially loose.  However, it is still a very useable source for information.  A necessary addition to your Triumph cycle reference library.  PayPal accepted.  Please add $2.95 postage for US shipments.  International bidders welcome.  Thanks for looking and good luck bidding!
