That ignition switch housing may have been from a TIII, but it looks the same as a TI of the same era. The ignition switch and lock assembly may be worth a few $ by themselves, but someone might need the housing too if there's was broken trying to remove it or maybe someone tried to steal the car. If it was mine (and I have a few laying around), I wouldn't expect to get more than $20-$25 for it. If it still had the turn signal lever in it, maybe $30-40.
