So several months back, I purchased a 1955 Biller Mechanical Dock Crane off Ebay after seeing a Japanese knockoff at a toy show. The thing was in perfect condition, but was missing the lift platform that came with it.
After scouring the internet and Ebay, I found some pics of a complete crane with the platform. I contacted the seller and he gave me the dimensions for the base. I then reverse designed the whole platform and created the pattern from the pictures I had and the two measurements.
The platform had a recessed area to aid in stability, so I created a crude die stamp from dense cardboard (a case from a replacement phone screen).
Here's the prototype.
Final pic is an actual platform for comparison
