This piece was made in 2004 and hung on the wall next to the door for a number of years. A little while back it fell or was knocked off the wall somehow and it needed repaired. I added a new bottom cluster to the piece and did some touch up painting and it's back on display in the newly redone B.I.C.A.S. Gallery! The chain ring on the top of this piece is a vintage skip tooth one that I found and had plated. The main piece is the back side of a chain guard. The bottom is a symmetrical gear cluster with a lock ring and a bearing for detail.
Chrome piece inside the chain ring is from a spoke guard and had plastic around it. The slender piece under the chain ring with the two bearings is from the front of the chain guard.
