[pianotech] Bridle-less Old Upright action

I tuned an old upright by Conover this morning, serial number 9880, which
places manufacture date in late 1880's.

One thing I found rather remarkable about it (besides the remarkably loose
pins!) was the action. I noticed there were NO bridle tapes at all. Further
inspection revealed 1877 and 1878 patents by Wessell, Nickel, & Gross, and a
rather "catchy" (if you will) hook on top of the jack which projects into a
hold in the rear of the hammer butt.

Of course I pulled out my camera to take a photo. Of course, the battery was
dead.

I will probably be re-visiting the piano in May or June so I'll get photos
then... but meantime, how widely was this action used? Any issues? I didn't
have to pull the action, so I can't honestly speak to its efficacy. Anyone?
