Richardson A600 Bowles-Acme Richardson animation stand. It has dual, traveling peg bars for shooting both 12 field and 16 field animation paper or inked and painted cells. It could be configured for 16mm or 35mm animation. The last ones were built in the 1960's.
Pegs seem to be missing from the peg bars. The main support arm casting seems to have been compromised. There appears to be a break in the casting where the north south platen rail is attached to the front of the support casting. The compound could still be usable but might have travel issues at different positions of the compound.
