A book was purchased at the Pier show in NYC this past January (22nd-23rd), and was subsequently lost. Leather spine marked "Winchendon, Central Stations" (or possibly Winchenden) Likely a unique copy, with typewritten pages of a course taught by Winchendon at MIT in the 1890-1910 time frame about power stations and engineering approaches.  Would appreciate leads from anyone who might see it in the marketplace. If you have any information regarding this book, please contact John Kuenzig, (978-887-4053) or orders@kuenzigbooks.com
