Like many of my modelling projects this one began with a decal sheet, specifically the “Fortress of the Skies Part 3: E Models” from Starfighter Decals. Mark has included eight different Fortresses on this sheet, all of them interesting for their camouflage schemes and / or service record. There are four different B-17Es in the Hawaiian Air Depot multi-colored scheme, two OD / NG, one RAF Temperate Sea scheme, and one HAD experimental scheme of overall Duco blue. Having already built an Academy B-17E in the HAD scheme, that left four to choose from. Choices like that are not one of my strengths so I chose two.

I have built both an Academy B-17E and the new Airfix B-17G. The Academy B-17E is the right version but needs several improvements to bring it up to speed, the Airfix B-17G is a really nice build but the wrong version. I decided to try backdating the Airfix kit to an E model. The Airfix kit comes with a Cheyenne tail turret, here is the tail position from an Academy B-17F test fit. Not perfect, but something which I could work with.
The Airfix B-17G represents a later production version with the staggered waist windows (why that wasn’t done right from the first E model is a mystery to me). This window will have to be filled and a new one cut further aft.
The earlier Forts had narrow prop blades. When the broad props were introduced with the F model forts the cowlings were shortened 3” to allow the wider blades to feather properly. In 1/72 scale the 3” cowling change works out to roughly 1 mm. Comparing the Airfix cowling to drawings it was unclear if the kit had it right or not. In the end I decided not to adjust the cowl depth. However, replacing the props is a requirement. Fortunately many of the Academy kits have both wide and narrow versions so I had enough.
The nose glazing is almost completely changed, and the B-17E didn’t have the Bendix chin turret. There will be some filling and cutting needed here.
Construction began with the tail position. I cut off the transparent upper portion, it was a bit too tall anyway and there is a nasty seam right through the middle of the aft-facing glazing. After gluing the halves together I braced the piece with plastic card to increase the diameter slightly to match the Airfix fuselage.
I then made an RTV mold and cast copies of the piece in resin. I needed two new tails for this project, and having the mold will allow me to make any of the earlier Forts right up through the first runs of the B-17G series.
I then set about moving the starboard waist gun position back. Here I am working through the fuselage from the inside with my trusty UMM scriber / scraper.
The forward opening was filled with sheet stock and superglue, then sanded smooth. I built up rib detail on the inside and installed the slide rails for the new window panel.
The bench in full modeling bliss. Various sub-assemblies are in progress, most notably the cockpit / bomb bay modules. Two rows of Quickboost resin engines are visible to the right.

I wish someone would make a 1/48 scale B-17 D and also B-17 E model kits.

If someone did a sharkfin B-17 in 1/48 they could get a B, C, or D using the same molds with a few odd bits. An E would be different but you could get to an F pretty easily with that one.

I would settle for a B, C, and D, and wait for an F. I have two Monogram B-17 Gs.
