100 year old sewing machine VS Brand new Singer Heavy Duty

In this video I will compare the skills of a 100 year old Singer 66 and a modern Singer Heavy duty. I made 5 leather bags with the machines, can you tell the difference in quality and design ?

I'm an engineer based in Europe. I made this channel to challenge my creativity and test my skills in all fields. Definitely building up some confidence in planning, definitely need more experience in execution.
Thanks for watching,
