Maria Mitchell Observatory and a Thomas Cooke telescope

 The Maria Mitchell Observatory was founded in 1908 in Vestal Street Nantucket Massachusetts. The observatory was named after Maria Mitchell America’s first professional woman astronomer. 

In 1952 the observatory housed a 5 inch clark telescope which was given to Maria Mitchell in 1859 by the women of America and used as a guide scope for a Cooke photographic triplet telescope of 7.5 inches aperture. 

I do not know when the observatory acquired the Cooke and how long it was used there if it indeed is still there today?
