My stand mounted 1953 vintage Model “A” measures 26 & 1/2″ from countershaft pulley to gearchange lever (it’s widest point).
Taking the countershaft off (2 allen bolts) should reduce the width by around 3-4″ can’t do much at the front to reduce the width as you have the gearbox and it’s levers in the way.
It’s not that great a task to remove one of these from it’s cabinet seven bolts and it’s off, if you wanted to strip further it’s relatively easy to remove the tailstock then the saddle (remove leadscrew bracket and slide off).
Removing the gearbox and leadscrew is nothing more than 5 allen screws but easier with an extra pair of hands to support.
Fiddliest part is the headstock front bolt I ended up bending a couple of spanners to do this.
Good luck

Paul
