This looks great!
But may I point out there is an error in nomeclature. Widespread, but still simply wrong.
187 is not the correct number for this project, this was developed under RLM number 287.
RLM number 187 was assigned to Focke Wulff, not Junkers, and actually used in the FW-187 Falke twin engine fighter. Each number was assigned only to one manufacturer by the RLM.
The 287 was assigned to Junkers and after early cancellation of this Stuka project later used for the Ju-287 jet bomber project. (the Stuka never got beyond a wind tunnel model so it was appropriate action by Junkers to "re-cycle" the project number)
At one time in literature, the misnumbering/typo happened and since then, the mislabeling was traded and handed down. Especially in English literature and websites it is very persistent. In German literature not so much anymore. The English wikipedia site is named Ju-187 and does not even mention this issue, it mainly quotes the erronous main source (Nowarra). Doesn't make it any more correct. The number is wrong.
The German wiki however is called Ju-287 and explains it.
Edit: too late I see.
paper project... it's a mute point anyway
