Brazilian RfP: Four Engined Bomber

Well, time to get the ball rolling.

In addition to the previous tender (which is now closed), in 1941 Brazil is also looking for a four engined bomber that can also be used in the maritime recon role. While I have a specific plane in mind, I do want to see what other ones are out there. No details on what numbers would be ordered, to be worked out later.
You smug-faced crowds with kindling eye
Who cheer when soldier lads march by,
Sneak home and pray you'll never know
The hell where youth and laughter go.

The French companies can offer some equipment for one or the other, and one or two planes which can theoretically do both - but they really don't have anything which does both jobs well.

Having supplied Whitley bombers to Brazil already the Air Ministry and the government give blessing for British firms to offer new equipment to Brazil.

Avro offers its new bomber, the 683 Lancaster; developed by Roy Chadwick this design is superior to the latest designs entering service worldwide and has a self-defence armament of powered nose, dorsal and tail turrets armed with .303in Browning MGs. The nose and dorsal turrets have two MGs each and the tail turret four; the bombload is 14,000lbs in a ventral bomb bay. A crew of seven is carried.
Dimensions; 102/ 69.6/ 20/ 1,297 sq ft; 4x 1,650hp Rolls-Royce Merlin VII; max speed 287mph at 11,500ft; cruising speed 210mph at 20,000ft; range 2,530 miles with 7,000lb bombload and service ceiling 24,500ft.

Boulton Paul offers the P.90 Birmingham; developed to Spec B.12/35 for a new four-engined heavy bomber to replace the AW. Whitley. This all-metal four-engined bomber has a crew of six and can carry 14,000lbs of bombs at 248mph at 15,000ft. The 28 500 or 250lb bombs are carried on Boulton Paul rotating magazine carriers and are interchangeable with other standard RAF carriers and carriers for seven 2,000lb bombs. Defensive armament is one nose turret with twin .303in Browning MGs, one retractable twin ventral turret and a Boulton Paul ‘dumbbell’ type tail turret armed with four .303in Browning MGs in stub winglets to cut drag. For the Brazilian order Boutlon Paul offers to fit RR Merlins if desired.
Dimensions; 100/ 77.3/ 20.5/ 1,450 sq ft; 4x 1,150hp Napier-Paxman Pilates II; max speed 290 mph; range 2,900 miles and service ceiling 35,000ft.

Italy would like to enquire as to what level performance is desired and as to whether a four-engined type is necessary.

For example, the Caproni 1001 Astore used by the Italian armed forces is a twin engined aircraft, but with similar payload-range characteristics to "heavy" bombers in service with other nations. In addition to this, it's in a package that is significantly less expensive to operate and more survivable.

A maritime reconnaissance variant has been proposed previously by Caproni but has yet (and may not be) adopted by the Marina Militaire. This version features a new forward fuselage with greater accommodation and vision, along with greater internal fuel capacity and new engines.
