Hi!

I was surprized too much while looking the stuff you posted.

I'm shure 100% you have a deal with WW2 army Mack model NR of about 1944-45.

Would tell you more if I see a better pic of the chassis number. But we can read NR in front of it and it makes sence.

Frame and the bogie look original, front axle, cab and the engine are aftermarket.

There was Lanova in it years back.

Front axle beam is different from a factory one with budds instead of original spokes.

Fuel tanks, running boards arrangement and the gear box are definitely of NR.

Congrats on the save.

Vlad.

the engine looks like my 673

[cncFireman]

very cool find

[BOB DINGSDALE]

It is a 673 top mounted injectors.looks to be a 53 truck or newer.cann't read chassis number because its to blurry.can you post it in writing.nice find though and I hope to see it again when its finished.

Looks more like a LFSW from about 1949.

Vlad, look on Page 66 of Barts Book. Same as the one in Scotland a few weeks back. Paul

Friends, I always take my hat off about your minds but this time it's recabbed and re-engined NR.

I don't be so shure if I haven't apart complete chassis up to every last bolt and nut spending many evenings to learn what place and way each of them must have.

The chassis number is in its correct place under the hole for pre-heaters cable with a content of about NR4D 9208D.

Paul, if you look on page 62 you can read "NR-14 s/n NR4D8567D-15646D. This truck is of the same butch as my one. With only difference of 1944 year of production instead of my earlier unit that came out from the factory on 19 January 1945.

Although where's the maestro with the correct ch.number?

AHHHH Soo. Think the center photo on page 63, of the NR with the post WWII Canadian cab MACK made for it is the same cab on this one? Paul

[Vladislav]

No Paul, page 63 shows vehicles with Mack L-series (factory) cabs. Many NR's were recabbed with them after the war because L cab was original to early series. An open cab had cowl and floor of the same kind as L-model. Edinbourgh truck has factory L-series sleeper cab, taller. But the black one you see high above has non-Mack cab. Although the cowl, the dash and the flooring are Mack and too probably NR.

The stuff that you have now is the NR chassis with aftermarket engine, cab and the front axle.

The early series NR's had a dash like in your truck wich is similar or close to L-series Mack. So it looks original. Original NR gearbox was TRD-37 5 speed duplex overdrive, always like the one you described. NR's were army trucks, they came all over the world after the end of WW2. Too possible some of them found their way to Argentina and worked there hard like many others in other such places. You noted for shure the cabs on both the trucks are similar. I have never seen such cabs elsewhere (in the net) but saw many other aftermarket ones. The truck I restore now was also recabbed and had it of Russian after-the-war truck MAZ-200.

So everything looks natural to me about this story.

P.s. The dash in the cab of a white truck is the NR later one. It relates to the 1946, the year of the latest NR-20 series.

Interesting that the last bunch of NR's (500 units) all came into France after the war for needs of French army.

That's a way to think of how this truck could go to Argentina.

[cncFireman]

Any idea who built the aftermarket cab?

new photos,with chassis numbers

[guille]

the engine looks like my 673

see new photos with engine numbers an chassis too

[theakerstwo]

That is a END 673 engine but not the early engine. The first 673 did not have a thermostat.If you look it has a by/pass oil filter and no full flow. On the bottom of the pan is a cover you take off and clean a screen ever time you change oil.

I have seen well everything you posted including the new pics.

Can't add anything new to what I said before.

The engine is Mack END, probably 673, I'm not the best specialist on them.

Although the original one was ED Lanova 519, had different mainfolds, fuel pump and many others.

ALL NR's were factory equipped with them.

They were not commonly used engines of later years and difficult to cold start because they were pre-chambered so I see nothing strange if somebody put another more modern Mack engine in the truck. By the way, they looked mostly similar and had many connections of the same kind.
