Unique Zeiss ERNOSTAR lens 1.8/24cm

Old Zeiss Eronostar lens. F=24cm, f/1.8. Very good condition.
We've found info in 2006 McKeown's guide that this lens belongs to 13x18cm Ermanox large format camera. There is no sales data on this camera.
But the same guide states that 6.5x9cm Eromanoxes were sold for $1800-3000, 9x12cm for $4800. No info on 10x15cm and 13x18cm cameras, but I suppose that they should cost even more. So, I believe that $5000 for this lens is fair price, and it just should wait to a right customer.
