Ok, shame on me. I've been sitting on this info for a long while... it's true my archive is in a pityful shape, the more since I digged unmercily it to extract info for ISP, but this is really, well...
Behold the MC-300. It did exists, and it was... a bomber. Subitted by Macchi to the Bombardiere Normale competition of 1938, not accepted in the first round (Prima Soluzione) and accepted but never ordered in the second round (Seconda Soluzione). Relevant data: lenght 14.00 mts, span 22.00 mts, height 4.58 mts, wing surface 55.00 sqmts, empty weight 6,150 kgs, MTOW 9,900 kgs, max speed 502.00 km/h at 5,000 mts, range 2,000 km, weapon load 980 kgs, 5 machine guns (see illustrations for disposition), 2 Alfa Romeo 135 with a nominal power of 1,350 HPs. And so this puts to rest a supposed "mistery", now, on, the next one....

Hello Skybolt,

do you know what bombsight was that in the second rendering? It looks like a telescopic one. Also, was there in Italy advanced bombsight and gunsight designs based on gyro technology?

Cheers

Really a astonishing find!
This development of Macchi for Bombers; I thought that only they had made ​​plans for the MC91/97 for the Concorso os 1934

@Wurger, yes it is a telescopic one. I don't know of any gyrostabilized bombsight in Italy during WW2.

Or MC.301;

Actually, the first competition...never was. There were successive spot requests from Regia Aeronautica to individual companies and some unsolicited proposal from individual companies regarding twin boom fighters, both original and derivative. Time span is from mid-1941 to first half of 1943. As for the MC-300, it never existed. The proposed (on exploratory request fro RA) coupled-fuselage derivative of MC-205 didn't even receive a numeral. An MC-301 did exist, but was earlier, and part of the Caccia Combattimento competition of 1938-39

According to the "Ali Antiche" magazine, the Mc.300 was the Macchi answer for a new medium/standard bomber required to replace the Savoia Marchetti SM.79 and the Fiat Br. 20.
Here the list of the competitors:
- Caproni Ca. 320
- Caproni Ca. 325
- Fiat Br 30
- Breda Ba 99
- SIAI SM.89
- Macchi Mc 300

Does anyone have some pics or drawings of the others projects?
Regards.

Well, since I am in the last mile, or half-mile in finishing Italian Secret Projects for Crecy (the title will be different, look out for the next printed nd onlne catalogue of theirs), I just want to put some things to rest regarding this topic. Macchi C.300 was bomber in the last pre-war comperition for a medium fast bomber (the "winner", in the sense that it was the last project standing, was the CAB Ca.325, the "real winner", in the sense that proceeded to be series-produced at least, was a last minute outsider, the CANT Z.1018, actually a secondo resort, since CANT firstly proposed the CANT Z.1007ter, then renamed 1015B, itself a derivative of the CANT Z.1015, born as a fast transatlantic mail carrier, then converted in a record-breaker, never used as such (ok, it's complicated, buy the book and everything will be crystal-clear). I confirm that the Macchi C.301 (btw, the MC designation never existed) was a Caccia-C for the second iteration of the 1938-39 competition. It was clearly inspired by the BF-110 and used surface evaporative radiator in the outer sections of the of the wings. It passed the first and the second selection, July and October (unlike the CR.50 and 55 and CAB Ca.350) but was eliminated during 1940, because it was too similar to the Bf.110 and the proposed substitution of DB.601 with FIAT A.38s never happned, since the A.38 never happened.
Finally, Ali Antiche article was based on the 1986 series on the Bombardiere 1938 by Giancarlo Garello. There are included all the drawings etc. Or just wait for ISP.
