"... I know you've probably heard it before, but if a list of REALLY GREAT horologists is ever done, your name will be at the top.  I don't know if you've ever replaced a spring, bushed a pivot or synch'ed a strike, but you've done more for horologists than anyone I know of in the past century.  And patriotism doesn't go unnoticed.  Perhaps more than being a great horologist, you, Sir, are a GREAT AMERICAN!..."
Colonel Larry Holmes - Clinton, MS

"... Your Seth Thomas Volumes were considered your finest work...Well, Tran, you have just superseded that publishing achievement...with your "Kroeber Clocks" book.  The amount of information in this book is astonishing!  Just when you believe you've seen it all, you publish the most comprehensive book ever for the Kroeber clock enthusiaist...Congratulations..."
Steve Sadowski - New York, NY

"... I deal with Ship's Bell and Ship's clocks daily and your Ship's Bell section is fantastic.  The only problem I see is that if collectors have your book I won't be able to get a bargain when buying..."
Earl Richey - Harrisburg, PA

"... The Movement section is incredible, how did you add so much information?  When I look at it, I can't say anything but Thank You.  You show a lot of guts when you reported on page 961 that Seth Thomas errored in their 1915 Catalog when they list the model applications for the 89-AD clock movement..."
Al Dodson - Clockmaker - Lexington, KY

"... I like your Watch Section.  In George Townsend's 'almost Everything You Want To Know about American Watches and Didn't Know Who To Ask', only three Seth Thomas watch movements are listed, but your Watch section has 41 different models'.  My hat is off to you..."
Denzil Miller - N. Ft. Myers, FL  Ditto:  Cooksey Shugart - Chattanooga, TN

"... With his new publication of Seth Thomas Clocks & Movements - 3rd Edition, Volume 1 & 2, Tran Duy Ly places himself in the ranks of recognized genius.  The sum total of all his many works on clocks has filled a void that no previous author or authority has been able to touch.  What a godsend for all of us in the field of repairing and collecting these wonderful pieces of American heritage.  Hats off, again, to Mr. Tran Duy Ly for yet another monumental work..."

Bob Schmitt - www.roschmittfinearts.com

"... I have always found Tran Duy Ly's books a very valuable source of reference for dealers and collectors here in England.  I have most of them in my library and never cease to be astonished that I can turn up an example of a particular model with an actual drawing of the clock from the original catalogue and even the original price.  What more could you ask?..."

Dave Ewbank - Avon, CT

"... OVERWHELMING!  The third edition for Seth Thomas Clocks & Movements by Tran Duy Ly and his staff cannot be described in any less terms.  Previously prepared editions by Tran represented the most comprehensive information published on Seth Thomas Clocks.  The last was {2nd edition} published in 1996.  This 3rd edition Volume 1 and 2 is so overwhelming in minute detail that it is a must-have for any collector of American  clocks..."

Well its here.  Trans new Seth Thomas book was on my door step this AM.  From 'American Clocks Volume One' Trans books have been superb.  This new book continues his great tradition.  Easy to follow as the clocks are all in alphabetical or numeral order.  This book has probably been the most anticipated volume he has produced.  The previous book has long been out of print and copies of it were reaching hundreds of dollars when they became available..."

"...He is both an American success story and a publishing marvel.  Perhaps not since the novels of Polish-born Joseph Conrad has any non-native speaker done so well writing in English.  While clock guides are not likely to be studied in English literature classes, Ly's prose style is clear, concise and readable without any of the anomalies one would expect of a non-native speaker.  Like a famous watch, Tran Duy Ly takes a licking and keeps ticking..."

"... Your clock identification and price guide books are the best guides on the market. They are accurate and complete and very well organized. Since I buy many of my antique clocks at auctions, the speed with which I can locate and identify a clock with your guides is essential. Other guides do not provide this organization and accuracy and require thumbing through each page of the guide looking for a particular clock probably not in the book. All of my old clock books are now obsolete..."
