Yes, I have a clear crud catcher and crud guard to sell. I cannot remember how old they are, but must be mid-late 90s. I think they must be the original type?
In good condition - they just need a good clean. As you would expect, the 'elastic bands' are missing from the crud guard. I seem to remember zip tying them on to the downtube once I had lost the bands.
I can post tomorrow if you need them asap. I will need to look into a price - TBH I was about to put them on ebay (hence I took photos on the weekend). I have a couple more close-up photos if you like.
