Searching for Kibri 6603 Gravel Tipple structure

I'm searching for a "virgin" kit of the Kibri 6603 Gravel Tipple building. If anyone has a heads up for me, please let me know.

If not in unopened condition, an opened but all parts present conditon is OK too.

I know Reynaulds & Euro Trains have them. I'm checking the private market first.

Thanks.

Murray
