Subjest says all. Can't seem to find one of these anywhere. I had one ordered from Selmer ages ago and I have given up on ever getting it. So if anyone has one they would like to sell let me know. I have a 180-37. Thanks!!
Did you at least get your money back from Selmer? As for the rounded tuning slide, I think that you can get them from Blackburn and there is another guy online that sells them. This is an online source for a "rounded" tuning slide, although it isn't going to be the single radius slide that I think you are looking for: http://www.electrotheremin.com/myslide.html Hope that helps.
I might consider Blackburn but it is a bit pricey!! I certainly don't want some rogue tuning slide made by some guy in his basement. I definitely want something a little more authentic. As for my money, I just put a deposit down for it at a local music shop and I can get this back at any point. I didn't think Slemer did direct sales?? Anyway, hopefully I can find one used somewhere online. Thanks for your time...
What bore size? ZeuS sells a single radius tuning slide for the Guarnerius (a Mt. Vernon Bach Strad replica). Single-Radius Tuning Slides      round bend, single radius crook .470" bore raw brass, raw brushed brass - $110 lacquer and brushed lacquer - $125 silver - $135 See: http://www.zacharymusic.com/Zachary_Music/NewZTR900.htm A couple left in .464 bore. Might be worth looking into if the bore size matches.
I have a very nice rounded tuning slide that I will be happy to sell to you. Send me a personal email, and I will let you have the particulars.
