I am original owner and this was my primary flash until I switched from film to digital about 20 years ago. It is in good shape complete with power cord and interface module for the hot shoe of canon cameras.  Battery compartment is clean - I always used rechargeable batteries and took them out after every use.  Head will swivel around in 12 positions, tilt from 0 to 90 and the diffuser has a zoom feature for 40 to 135 mm.   Powerful with a guide number of 120 (in feet, at ASA 100).   Instruction manual included.
