I painted the interior and did some detailing. As it turns out, that is all time wasted, given that once the canopy is on, you cannot see anything other than the cockpit that is immediately visible under the canopy. So, do or do not, but know that it will never be seen again once the fuselage is closed up.
Closed up the fuselage, and found that to get the side glass in the canopy to stay in position, since the joining surfaces are very small, was best accomplished running a thin line of CA glue along the side piece, using the pointed end of a pin as the applicator. I closed up the bomb bay just because I wanted to preserve the lines of the aircraft. The bomb bay has nice interior detail and provides 6x1,000-lb bombs and a 5,000-lb "cookie," the standard Lancaster load.
H-K really has figured out how to make it so the wings and tail do not have to be glued into position. They slide into their holders and "click". No sag, a very solid model when you pick it up, yet a model that can be stored in a box when not on display. The props also are slip-on/off.
Something to consider: early B.Mk. I's had the small fuselage windows; these were later replaced with metal. However, also, some of the early planes when they were reworked had the windows either painted over or replaced with metal. Also, most B.Mk.Is had the side window with the teardrop bulge, while B. Mk. IIIs didn't. But some B.Mk. Is had the side window with the bulge replaced. You need to find photos of the subject matter you are doing to figure that out. Fortunately, I was able to find photos on the net of the two airplanes that are markings options in the kit, as well as the markings options in the Xtradecal "Ton-up Lancasters" sheet I will be using. The time spent doing that research is time well-spent.
Now to proceed to attaching all the small detail to the fuselage that Tamiya didn't even provide.
