Here is a nice one currently in the classifieds.

All the examples I have seen have been either early custom shop super grade guns, the early custom classics, or early 5 digit classic supergrades (such as the one above).

From a date range, that would correspond to ~’88 for the earliest custom shop CRF guns to ~ ‘92 for the example above.
