I am selling a doublet refractor lens in cell. It is a D&G 5" f15 hand made in the USA and I am the original owner. The lens performs very well and is excellent for astronomy giving very sharp and clear views of the moon and planets and DSO's when sky conditions allow.
Please refer to this link for more information;

These lenses are difficult to get now and when they were last available wait times were many months.
The price is $925 including postage in Australia.
Please send me a private message PM if you are interested.
