Not of the highest importance, I realize, but I have these old pedals I got in a box of parts. The only identification I can find on them is "West Germany". The clips are Christophe, but I suspect they were a later addition. One is missing a dustcap, but I went ahead and repacked it anyway. Are these things (dustcaps) universal? Do I look at my LBS's parts bin? Anybody have any experience with these pedals or retrofitting dustcaps?
