Recently Nordmark put out a request for bombers. The medium bomber request I found I could meet by expanding my T.VIIIW design, a descendant of the T.V.

The heavy bomber was far more ploblematic. In 1934 Fokker had the Design 115, based on the F.36 airliner. Trimming the giant wing and the plane met the range & speed, and almost the height, but failed the bomb load. These two designs are powered by Avia's versions of the Bristol Pegasus radial, and so should need little alteration to fit the Spartan.

So it got reworked to a much larger plane, Design 119, that meets the bomb load & range has room for expansion, but doesn't meet the speed or height requirements. However performance figures are based on the Jumo 211A, which is an immature engine and so performance specs can be expected improve with the mature engine.

What´s the photo from?

The photo looks like the T-5.

Close, the T.V's successor, the T.IX.
There's just not a lot of OTL dutch medium bombers to choose from.
