Hi Guys. Its a 1975 Conn 73H, Double plug, Bb/F/E and with the included extension Bb/F/D. Its one of the trombones made in the "Abeline" plant just after the "Elkhar" plant had closed. Its a good one, and has the Elkhart engraving. 9.5 inch yellow brass bell .562 bore Slide just serviced In original case Excellent condition for its age. Owned by "Gentleman" John Hendy of WNO until 3 years ago when I swapped it with him. Im looking for 1500 ono for this, which I think is good value considering the rarity, and the price of a new trombone. Il always consider a Conn 8 or 88 in part ex. It looks like this: http://cderksen.home.xs4all.nl/Conn73H1968image.html Please send me a PM or even better a text if your interested or for photos etc. 07977042896 HAGW Jon.
