There were a few of these CZ models in crates floating around years ago, Drakie had a 513 still in its crate for many years then around lat 90's/early 2000's had a 'uncrating' ceremony that was celebrated with much alcohol and burnt meat offerings while the assembly took place and then it was ridden around his backyard.
I had some photo's of this great mens ritual but can't find them at the moment.
Pretty sure he lost interest in it after he rode it and he moved it on but he still may have it.
