The Wite2 data has the SM.82 range listed as
1033 miles, and
1488 miles (with aux tanks);
However, the consensus is that it is has a range of
1864 miles.
I have a compiled a spreadsheet, listing specification data from six other sources and have placed here for reference:
https://docs.google.com/spreadsheets/d/ ... sp=sharing
The engine appears to be one of (Alfa 128 R.C.18 / Alfa 128 R.C.21 / Alfa 129 R.C.32)
see
https://www.wikiwand.com/en/Alfa_Romeo_125
Wikipedia is somewhat of an oddball and is conflicted regarding its cited range, as it only lists a range of
1300 miles, yet asserts the following:
This meant a flight of 4,200 km (2,610 mi), lasting 15 hours at 270 km/h (170 mph), that was for the time arguably a record for a bombing mission.

My bad. Try again.
My intent was to make it "read only", but not blocked.
I cut & pasted the content below, but the formatting is really horked if not viewed via a spreadsheet.

A little off topic, there is an amusing account of Mussolini begging Hitler to transport a bunch of stuff from/to Albania & Italy, in support of his floundering invasion of Greece (1940).
At first glance, the SM.82 appears much more capable. However,
the Italians claimed that the Regia Aeronautica’s Savoia-Marchetti S.82 transports were not available because of commitments in the Mediterranean and Africa.
Additionally, from the accounts I have read, it appears the SM.82 practically
self-combusted at the first sign of enemy fighters. But the Ju-52s appears to have had no issue.
Once missions commenced, there was no interruption from enemy aircraft, either in the air during the 320-km flight to and from Tirana, or on the ground, with the exception of one RAF bombing raid on Foggia, which failed to inflict any damage. Formation flights were usually made in daylight in Ketten of three aircraft, each Kette taking off at five-minute intervals. During the first phase of operations up until mid-January 1941, the Ju 52/3ms achieved around 100 flights per day, reducing to approximately 60 during the final weeks of the operation, but there were ten days when adverse weather precluded any flying. Over a total of 50 days of flying, III./KG.z.b.V.1 flew 4028 sorties to Tirana, of which 1665 were predominantly troop transport and 2363 were mainly for the ferrying of supplies. Altogether, 28,871 Italian soldiers were ferried to Albania along with 4700 tons of supplies, while some 10,941 personnel, of whom 8730 were wounded, were brought back to Italy. No aircraft were lost during the Tirana flights, which, while undertaken in conditions akin to peacetime, nevertheless provided invaluable experience for later Luftwaffe transport missions to and from North Africa.

Don't forget they have taken off from Rhodes - and landed in Eritrea after.

At 3 a.m.I was too lazy and hoped for someone to add the missing part of the route. Since I didn't know I can measure multiple "direct-path-point-routes" I throught I'd have to edit the picture.
But just adding a new measure point works, learned smth.

You are correct sir. I read that account as well. That was an impressive flight.
