I have what I think are the original paintings for the covers of the Astrocrane and Astrodigger boxes. They appear to be water color or gouache. They are both signed by Frank Tinsley. How do I determine what they are worth? Owen Resh (email@example.com).
I have a “Ring A Peg” game by The A.C. Gilbert Co. and haven’t been able to find any information on it. I am hoping you can lead me in the right direction. Thank you. Christel (firstname.lastname@example.org).
I have a microscope and lab set. A Gilbert Career- Building Science Set with all pieces no.13025 60-90-400 power electric microscope and lab set with 3-way electric plug in light. Please contact me. I would like to know what it’s worth. Thanks so much, Reda Jones (email@example.com).

Before building this crane, I looked at several crane designs on the Internet and incorporated some of the designs in my model. I have given my crane the name “The Mammoth Crane”, representing the new generation of 200,000 ton heavy lift cranes. These are cranes which are platform twin-rig containerized. In the PTC design of these cranes the boom height is as high as 587 feet. In addition, these cranes can lift in excess of 3,500 tons.
My super heavy lift crane weighs about 125 pounds. Over recent months I have taken it through a number of tests. Upon performing a heavy lift test in August 2014 I successfully lifted 40 pounds. This was done with the use of 5 gallon milk jugs filled with water. The boom height of my crane is 8 feet and it has 4 two-speed hoists and 5 motors.
