Take a look at these and see if any match yours. I have the case15 with the sticker and it was sold separately from any set.
Does anyone know if there was ever a lego set released with a large red plastic case? I bought a case full of legos from the thrift shop the other day and don't know if the case was something that was usually sold separately or if it was included in a set. Looks like several large pieces to a boat / barge inside as well.
It didn't take as long as I thought it might. You can check out the answers from 2 of the people who did the peeron inventories and my own research in this BrickLink thread. http://www.bricklink.com/messageThread.asp?ID=215614&nID=1023329
Rebrickable's Build Function uses the parts needed to build a model using the Set Instructions, so I'm inclined to add the 3rd radio as an extra. However, I'll give it a few days to let others add their opinions here.
I use https://github.com/marcgibbons/django-rest-swagger to auto-generate the documentation from my code, but I don't think it supports much of what you're after eg https://github.com/marcgibbons/django-rest-swagger/issues/583
That's a nice editor, perhaps I can just do it manually once the API is finalised
