Looks like new having had little use, but many hammers won't return, and at first I thought the pinning was too tight, and/or just sluggish from non use and excess humidity, but then I noticed that there are NO bridle wires/straps at all. I've seen a few spinets without them before, but not very often. Any advice on getting the hammers to return, short of retro-fitting a whole new set of bridle wires and straps? I thought maybe strengthening the hammer springs and appling protek to all the centers might help as well.  What's funny is that the whips have the little holes where they would go, but they were never installed at the factory.<span class="Apple-converted-space"> </span><br><br>Thanks,<br><br>Terry "UniGeezer" Peterson<br>"Over 50, and not '2' Tired!"<span class="Apple-converted-space"> </span><br><a href="http://unigeezer.com/" target="_blank" style="font-weight: bold; ">www.unigeezer.com</a></div></div></span></blockquote></div><br></div></body></html>
