I believe I spy a remote valve on the right side of the lift arm on the picture that shows the rear of the tractor but it's hard to be sure.
Regardless of the HP, although the 27hp do make sense, this is a lot more tractor than your current one. It has a lot more weight, so it can handle a lot more weight on the 3 pt as well. On the picture, it's possible to see the gross towing weight of 3125kg along with the weight of the tractor, 790kgs. This is about the double the weight of your current tractor.
I would expect it to have a 9F+3R transmission or even a 8F+4R but then again, very had to find a catalogue of this tractor.
Some time ago, I saw an Antonio Carraro 2700 on the road with a 3500 kgs trailer fully loaded to the top with logs. That thing was ripping at top speed.
By the way, if you end up making the deal, make sure the seller has the ROPS. For some reason, someone took it off and I'm sure you know how the rules are lot tighter regarding ROPS.
EDIT: Found this ad in Italy, the seller lists a Ruggerini 26hp engine and it has a picture of the gear shift levers where it's possible to see 6 forward gears and 3 reverse gears.
