Hi new friends! I'm very new to leather working, sewing machine repair and this forum! I'm a huge fan of mechanical things but have little experience. I was able to get my hands on an old Pfaff 145 for $200 and am attempting a restoration. The first thing I noticed is that the decal is very gently applied and I'm nervous about washing the machine. Is this something I should care about? The machine is in kinda rough shape (cosmetically) and I'm not sure the best path forward to restoration. Is it important to not change anything about the machine and try to save as much as possible? or is it ok to repaint and cover up the imperfections to stop corrosion? Pics if they're helpful and thanks for the feedback!
