Good news! the fit is almost perfect with this attempt.




The Air Master set for the Parabellum 14 & 14/17 guns are shown add to the basic WNW kit items.

Greetings Terri,

Yes, I intend on further detailing and even a bit of gunmetal dry brushing.

They look just great Stephen obviously still WIP but those barrels just give them that extra zap.

On the Roland I tried washing the blued areas witth Blue ink from Citadel, I got a reasonable result, one I'm going to experiment further with.

Looking forwards to seeing you do the mod on this one.

The lets move on! My next move is to build a mock up of the cockpit interior and save the kit part til I am sure of cuts I need to make. Always keep scrap sheet plastic! It comes in handy for these things.

A magnificent beginning, sir...

I noticed that my lower wing does cause some minuscule splitting of the seams when dry-fitted, along with major excavation of the fuselage mount to get the center portion of the wing to seat properly. No problems with the upper wing. I guess it depends on the mold.

I will continue to follow your build closely.

Quoted Text

Images here are from the WNW site and were taken by Giorgio Dorat. They show the rear cockpit of the Junkers J.I in Milan. . .The divider wall between the front and rear cockpit has been removed to accomidate the twin parabellum installation. . . "







Some more WNW images to ponder.

As you can see some attempt has been made to repaint the basic colours on the outside.

But significant colour notations for the interior need to be observed.


They also seem to have repaired the instrument panel in the pilot's cockpit. Now when you see the images from the WNW instruction booklet you see the original state of deterioration and the extent of how differently the paint was applied to certain areas.

Note the white areas near the rear cockpit flooring and on the twin parabellum supprt frames are white (well worn but white).

The two images shown here are at the bottom of the instruction page 18 tend to show Junkers J.I 816/17 before restoration began.

Ok here is some progress.

It is not yet glued in place here so I can push it in further.


Here I am checking the angle of the gun with the hole.

Here the clearance holes for the bullet path are plotted upper surface lower wing.


Here the clearance holes for the bullet path are plotted under surface lower wing.


These next images show the basic colours of the interior of J.I 816/17 and the modified instrument panel. The PE Bosch starter magneto is from a left over Part of Paland brass set . The kit item was removed. The current restoration on the original shows this starter mag has been moved to the new location.


There will be some white portions added to the rear cockpit per the original airframe. More to come.

I have had to rethink my appraisal of the Parabellums being used in this Junkers J.I. Several things have changed my thinking.

1. WNW Richard Alexander's e-mails
2. German munitions expert Dave Watts e-mails.
3. This image.
4. A possible image I am seeking from Harry Woodman's archive.

One or both of these may have been the late Spandau Maxims that were the 13mm bore. So instead of the Air Master Parabellums I intend on using the Air Master Spandaus. Also over all they fit better than the Parabellums. Next to work out the triggering mechanism.

Recent research has proved to me at least that the 13mm Maxims were not used on this machine. So I'll be using the Air Master Spandaus.

Looking forward at the various angles that need to be negotiated for the Spandau Maxim gun support framing.



Working on the bits and bobs. Anything metal gets a coat of Testors Aluminum (buffable) and a coat of clear Dullcote. Next the Basic colour. The engine access cowls are being simulated to have heat distortion in the basic colour.

Greetings all,

The build does progress. Images to post in the next couple of days. I am almost ready to close up the fuselage now. The cradle has come together well enough but I had to modifiy my early assumption that downward firing Parbellums were used when in fact it was Spandau Maxims. So I have switched from Master Parbellums to their Maxims.

Good news! The rear cockpit cradle for the downward firing Spandaus is almost finished. I'll have some images in the next couple of days. I am trying to finish up some of these cockpit details. Then on to the engine.

Well then I guess I should start. First to custom fit a scratchbuilt gun gradle I have to have some info. First the area inquestion needs to be plotted.









Here from the Flight Magazine of 1919 is the Close Air Support Gun Cradle from a late mode AEG J.I and is similar to the one seen in this thread's WnW images of Junkers J.I 816/17
