Restoring early Shimano 600 derailleurs

I'm terrible at before pics but I snapped a couple of the aftermath; the Arabesque one was very rough, cracked plastic thing, bent stop on the mounting plate, totally frozen pivots; I was able to get it apart and clean it all up and it came back very nicely, pick out the best pieces to put it back together with and that's one done, had enough pieces left over to complete a good regular 600 one as well, sacrificed the damaged 600 and a NOS Altus for parts 🤠🤠
