This listing is for (1) 100% NOS remote control assembly lead. It definitely fits the 1215 Computer II analyzer. This lead is in excellent NOS condition. This is one of many items I've acquired from a retired distributor's remaining stock. No returns. No refunds. There is no mystery here. No cancellations for accidental purchases. What you see is what you get. Check my other listings for more Sun Electric parts in the coming days and weeks. I always combine shipping and refund the difference.
