Information on Saab J-27?

[Chilli_Choccies]

I am looking for information on the development of the J-27, specifically if any portions of the aircraft were ever constructed (even at a mockup stage).
I know the plane was never completed but I don't know if any parts were made - can someone help me with that?
(also any other info will be great too)
I've done as much research as I can do but the information is so so sparse

Currently I have information on the design specs and armament, but thats about it

Sorry, nothing best

- At the end of 1944 the latest models of German and British fighters already reached speeds that the J 21 could not match, because of the excessive drag generated by their tail surfaces. In April 1945, SAAB started the design work on the J 27, a conventional fighter with elliptical wings, Youngman flaps, tear drop canopy and ejector seat, capable of flying at 700 kph powered by a 2,200 hp Rolls-Royce Griffon engine driving contra-rotating airscrews.

The foreseen armament was four 13.2 mm Bofors-Colt m/39A wing-mounted machine guns.

It was expected to build a more advanced version, with butterfly tail, four 20 mm Hispano cannons and 740 kph maximum speed, when the 2,500 hp Svenka Flygmotor AB Mx would be available, a 54 litres engine with 24 cylinders in 'X' configuration to be ready in 1947.

At the end of 1945 the Flygvapnet chose one brute force solution, acquiring the manufacture license of the Havilland Goblin Mk.II British turbojet (1,360 kg thrust), to power an advanced version of the J 21 that flew at 800 kph in 1947.

The only source I've found is this, which doesn't say much more than what you seem to know, but it does say more about other unbuilt Swedish aircraft
