Thats a mk 4 Escort one you got there(5012676) only diffrence from a MK3 item is the horn push/mk 3 just had a pad the bosses are the same for mk 3 and 4.
Got to be worth £250 + IMO as i sold them before very easy for £250 even without a boss.
These where around £170 new when you could buy them all thoses years ago from ford at least 10 years if not more where the last time they where avab.
