Nice find. Unfortunately, like most metal lathes, the size advertised (40.5") is not the length between centers. The specs show it is 750mm b/t centers, which is less than 30". A prudent buyer would get written confirmation as to whether that dimension is from the front of the chuck or from the front of the spindle opening.
Another concern is that even though specs indicate the spindle through hole is roughly 1.5", the 125mm chucks
generally have a 1.125" through hole. Again, get confirmation for the chuck through hole size. An option might be to upgrade to the larger 160mm chuck (if it fits) or bore this one out for use (if possible).
One of the sellers is in the US, if someone cares to find out more info.
