Fellows,
I work for the CSIRO Australia Telescope National Facility (Narrabri) as a Cryogenics Officer and in my travels I came across this old warhorse at Parkes.

Speaking to the older members of our group it has been there a long time and I would hazard a guess that it was used in the construction of the telescope in the early 60's plus used as a crane truck until new HSE regulations sent it to the scrap heap.
Please see photos.
BTW it is definitely "NOT FOR SALE" otherwise I would have added it to my collection by now
Cheers
John Wilson
