A couple of more detailed pix.

Recycled Blitz parts are evident.
The only problem that I can see if it were a forklift is the absence of any mechanism to keep the forks horizontal... Maybe there is another ram missing?
The owner of the 'thing' was told by his father that it was a bomb-lifter??
Would I be correct in thinking that this is post-war construction from disposals parts?
