Patrick, that machine is restored by Andrew Hills, he is located in England. He has an Instagram account that is worth following and restores similar machines on the regular including the full range of Wadkin Mortisers.
I thought the lack of tilting table would hamper my use of the Wadkin, but it does not. Rather, I make a wedge then use that same wedge also for cutting tenons. I find it helpful as the angles are always the same and I don’t need to reset any of my fences.
In the machinist world it is common to leave the machine as is and use an auxiliary tilt table to accomplish the tilt. This is done for multiple reasons and one of the majors is that people often do not want to retram the machine each time they need to adjust a table. The same reason one avoids taking a saw fence out of square once it is made perfect.
Bumbling forward into the unknown.
