About 7 foot long. Three foot deep including all handles, coolant tank and the motor hanging off the back. 2 foot if you remove the forward/reverse lever and the motor etc.
Both have been painted which I would always be dubious about. perhaps there is a kind hearted forum member nearby to the seller who could give them a look at and help to form an opinion of their true condition. A painted-up worn out lathe is no better than a worn lathe.

Just my two pennorth! with a SC gearbox, you can only cut the threads in the gearbox, with changewheels, you can cut any thread in the universe, but really the only difference is how many threads do you need to cut? it is only when you are matching an existing thread that you need to be specific, if you are cutting both sides, you can use what you got!

That statement is roughly 1 1/2p wide of the mark.
Very much relevant to the machine in question here, look at Mr Doubleboost on youtube. He has a metric Harrison 140 and cuts a wide range of both metric and imperial threads all the time.
It might be a more useful service to the potential buyer to look at the manuals/data plates for the two machines, see what pitches (imperial and metric) that they can cut and highlight any useful/common ones that are missing and that might cause him aggravation in the future.

I was leaning more towards not being put off a lathe because it has no SC box, provided it has a full set of change wheels, if indeed there is such a thing! The Harrison is the better machine without a doubt, provided you can cope with the weight and the footprint.

Change wheels are easy and quick enough to swap, get the Harrison.
Theres a good website, ridethegeartrain that simplifies setting up about every pitch you could want to use.
As much as I'd like a bigger workshop and lathe, I can do pretty much all turning I want on my chinesium 10" which is about 1 meter long by half meter deep, can be lifted by a single person, fits in my tiny shed, but due to demand they are rarely any cheaper.
The advantage of a bigger lathe will come if your turning over 160mm dia or longer stuff.
What do you plan to turn?

Harrison is going to be the stouter machine, no question.
However always buy on condition and tooling - I'd rather have a well equipped mint Boxford than a knackered Harrison with a worn out 3 jaw!

Which supplier are you using? Is it the guy in the Ards area?
Have you tried Kenequip/ Harrison brothers in Longford?
https://www.kenequip.com/
Got a good reputation & have a good selection of used machinery plus parts backup if it goes wrong.

Both machines are from england I've got to Monday to decide waiting on a few more quotes for delivery, the Boxford is a handy size and cheaper to get here etc but the harrison is a more substantial lathe with
More tooling hoping a decent engine lift will get it of the trailer after that it'll be on rollers, where as I can split the Boxford and get into place easily, most threads on this site ends with I wish I had of got a bigger lathe, that's what's swaying me towards the harrison

750 isn't a limit and all it is, is the pulley on the motor. Slower for school use. They'll take 1500rpm on the standard bearings.
One thing you really must check, along with general wear. The condition of the L00 taper. If that's **Language**ed your chuck will never go back on the same twice ruining any repeatability.

Reading around a bit, it looks like they made them in two 8 speed options and a 16 speed with a two-speed motor, with the lower speed, basic model aimed at schools and training establishments and the higher speed aimed at industry. That might be in your favour as a school one should have had an easier life.
From what I have read, it was just a different motor, different drive pulleys and a different data plate. The headstock bearings in particular were the same.
There's a manual at vintagemachinery.org but it is a bit jumbled up as there was never really a 140-specific one. If you look at the picture of the data plate for the 16-speed one below, it is the just a 750 with two speed motor. If you have native, full fat 415v three phase, it could be as simple as just buying a new motor. No new wiring or control circuitry needed. If you are running from a VFD, just buy a 2800rpm motor and have infinitely variable speed from less than 34 up to more than 1500.
There is a Harrison group at groups.io so you could read their back catalogue of messages to see if the issue has come up before.
A previous discussion here:
Harrison 140 Motor Frame Type
Does anyone know what sort of motor I need to buy? There seems to be a number of frame options. Do new motors come with different spindle sizes? Any motor brands to look for? I’ll be running it on three phase mains supply.
