FS Promaster 6500M flash for NIKON TTL. I used it on my Nikon N80 and on the N90s as well.

Full disclosure: The red IR lens just fell off one time for no reason. so a dab or rubber cement on a tooth pick was used to put a bead of glue on the lens mount and has worked find ever since. No issues. ( share this because no one especially me likes surprises, the fix effects nothing and you have to look for it to know it happened)

Good working condition
