Pfaff left hander rebuild from a shed

I have found this really old Pfaff rotary machine on sale from a shed rusted to dead stiff when i was looking for my first leather sewing machine. The state of the machine was a big turndown for the first time but it was a complete time capsule from an old shoemakers shop so i could not resist to make a deal on it and try to get it working again. The artwork on the machine is hand painted i think with shellac base and pigment and over the years the laquer turned into a solid layer with the oil residues. If anyone has pictures of similar paintjobs any help would me much appreciated. I think it was a rare option when the machine was new and i cant really find any pictures on the net what i could use for reference so its not going to get painted for now.
