Re: Ju 88 Werk-Nr. 790

Hello, Leaving you guy´s alone for a few days to go to BA-Militararchiv in Freiburg and everything goes wrong. Now I set this straight.

The Ju 88 D-2 was just that, own independent version, without Dive-Brakes but retaining glide or level bombing opions. Full sequence 0880798 and shared the Ju 88 A-5 airframe (Jumo 211 G engines) and equipment with a differance in main Camara equipment location, just as Ju 88 D-3 of 088043xxxx (aka D-1) was equal to A-4 in 088014xxxx and C-6 in 088036xxxx / 75xxxx with Jumo 211 F/J engines. Diffrence of A-5 F and D-2 was location of its Rheinbild 30 cm VERTICAL MAPPING cameras, now behind the rear bay Spt. 15, like the C-4 could have one, and C-7 also one (both that could carry fuel tank or boost tank in rear bay for more range/speed). Old Ju 88 A-1 / A-5 F had cameras inside rear bomb bay. (But goghs number sequence and timing for Ju 88 D-1 088 043 0001 to 0960 series is wrong. I separate this for explanation of how this was made up. Ju 88 D-1 assembly starting in October 1941 and series extended to June 1943, and ALL numbers used, just not starting at 001. None of 043, 014 or 036 ranges did start at 001 and one had quite large blank space, fooling ArtyBob in his book because he simply did not do his homework properly. Many of his "tables" in this catagory are pointless, wrong and false. Usually his tables are one month off, because he equals production with deliveries. And there was still summer vacation period 1941.

And I started by making my own production lists, now with all tables verified and correct quantity for each block or batch. And now for next few weeks I am puzzling togeather all the quirks and oops of the Lieferplans, that so far most have used incorrectly because very few present day authors know how to read them. Some plans were not used at all, others changed in middle of a month, yet most endured a month or two, three at most. Comparing delivery figures to planned thus quickly gets muddled. And one peculiar thing appears. So and so A-3 were ordered, X numbers delivered, yet A-3 total numbers became much higher. No new delivered, because execessive ones were made up of Reparatur machines, converted from other version at same time, throwing all "total built" out the window. So one enters Total, Total conversions and Grand total built, and not adding up. But thats correct!

Reason for above is that the opposite was true of 043 range, many D-5, H-1, H-2 and other versions were from this range. And conversions to T-1 and Ju 188 F

Null here designated Junkers as maker. Saying 430xxx or 798 skips the factory designator and true correct is 0798 for the D-2 series that preceeded the D-1 - remember D-2 before D-1 and A-5 before A-4) any other use skips maker and is faulty, because here Null has all the meaning. All maintenance and modifications (Änderungs Änweisungen) depended on this, also TM notes (like used today in the light aviation world) also depended on correct use of W.Nrs. AND batches, behind all was Serial numbers of all components, including wings and fuselages, that were quite indpendent to Part Number system (8-88.xxx-xxxx) but often intregrated.
(No dot, remember NEVER dots in any Ju 88 W.Nr´s. Simple enough to remember.)

But, if anyone asks, BArch personel was very friendly and warm. And housing good, clean and enough space, and plenty of university student visitors watching us researchers going full pace - others just quietly digesting obsure papers about things of the past. Climate was a little too hot at times, +29 DEG C tends to be such, but a Vending Machine with cool sparking water/soda saved the day again and again.
