An example of an A.R. Brock Harp Guitar surfaced at a Texas Guitar show in 1996. The instrument's only company clue appears on the headstock, and reads "Brooklyn, New York." The guitar was decently built, and sounded okay when plugged into an amp. Any further information on A.R. Brock can be submitted directly to Blue Book Publications.
Instruments previously built in Brooklyn, NY, unknown production date.
