I too had the "spy" version. Built it many years ago.
I didn't like the cabin/ bridge section, so I scratchbuilt my own that backdated the kit to something from the early 1900's
Sorry, no pictures of it ( it was back in the early 80s, and I was prone to succumbing to the use of fireworks.)
I do not recall any problems with the kit, other than the ones I created for myself.
