As said above for any relation to rust.

Looks cool. Tough as a small bulldog:)

 

What is the source of blue smoke on the 2nd and 3rd pictures?

My R model was running

What engine it had? Was it cold after start?

My interest is not because I dislike smoke but I would like to know the reasons my one does it.

If you blow smoke like that and the motor is i  good order I reckon you will find the motor is glazing up due to not been worked

I have two old 237 horses, used as yard trucks once in a blue moon.  They both smoke. Never get worked hard. Injectors good be lazy and worn out, sleeves could be worn out or need to be re-honed, valve stem seals could be dry rotted and leaking oil... (I forget if these engines even use valve stem seals)

If I re-honed them I'd have to do the brake in procedure which isn't possible on these.

It was only smoking because I had just started it cold. 5 minutes down the road no smoking.  Its a 673 250 horse built just before the 237 came out. 

Besides, it's an old Mack it's supposed to smoke 

I like the look of that blue R.

My personal preference is the later series but the earlier ones look nice and very nostalgic.

Got about the smoke went away after some driving, thanks.

Wait a second!

It's been to the New England show a couple years ago and Macungie last year.  OK. So, it went to its first show THIS year.

I see Herbie, Victor, DC and Red Horse taking pictures.  That is a fine looking patch of grass. Where were you boys hanging out?

It doesn't cost anything to pay attention.

Collings foundation American Heritage Museum in Hudson.  You should see the tank collection there.
