I have opened and used Parker Majestic surface grinders.
PM's were the Cadillac of surface grinders.
They have more cast iron ,which makes them more stable.
The quality is/was unsurpassed.
700.00 is a good price and the spindle cartridge can be moved in and out( not during grinding)
The cartridge can be sold currently for about half that price.
The mag chuck and control about the same.
This looks like it has the vertical power feed, far right handle.
Surface grinders have become somewhat obsolete by the introduction of hard turning and incredible advances in tooling.
I have some left over parts and I see used parts on the bay.
One word of caution They are generally heavier than other makes.
