This is what I have heard. If you purchase a KV track, it comes named as the order number to the purchaser. I have in the past mentioned that, to those who are gracious enough to offer their KV tracks, to open the zip and use the number used inside the zip, as that is the actual catalogue number. Offering up your track, with the original name at purchase time, may open you up to KV tracing who the track was originally sold to. Check it out the next time you purchase a track. Cheers
