I think you did alright for sure. Replace the string, and it looks like you have a plunger typre rest on there but I can't tell for sure. Pull that off and glue a piece of felt right on the shelf and shoot off that. You will have to use real feathers on your arrows though. As C68 said, I used to build my arrows too. With a recurve you can shoot wooden arrows. It's fun to build your own, you just need a few specialty tools. Talk to someone at your local shop about ordering Cedar shafts in the correct spine, (flexability of the shaft) and some instructions on how to build them. I use to shoot cedar and maple. The maple shafts are very slow and heavy, but they hit hard! The cedars shoot very flat and fast. They are more delicate however and won't put up with alot of abuse. 50 pounds in my opinion is powerful enough for a recurve, so don't worry about that either. Congradulations on the find and have fun.
