1972 & 1959 Conn 78H Trombones restored + compared (.522 bore)

I purchased two professional (.522 bore) Conn 78H's from 1959 and 1972 to refurbish & restore. I do a playing comparison after I show the work I performed on the trombones. The 78H's produce a richer & bigger sound than the 6H, but lighter and less weighty than the 88H's. These are for sale so feel free to message me if you are interested.
I will be positing these up on Reverb in the near future of you can buy them directly from me now.
