Don't know the diff between those two but the diff between the 71 and 73 is mostly styling and a large increase in decor stitches.
The 1471 is an excellent machine, I use it exclusively for lightweight leather; from 1mm - 1.5mm.
The 1473 will do the same job for me if all goes well.
My career long devotion to Human Factors is also in play; all of the flat buttons have been replaced from the 71 with nice proud of surface buttons. These are esier to see and feel. The color choice is also more inviting.
On initial trials the needle threader needs adjustment and it needed new AA batts
It runs smooth and quiet. I think I am totally sold on IDT and won't consider anything without it.
Made in "West Germany" is one of the vintage aspects of this machine that seems to intrigue people; not sure if all 73s were pre 1990 but I think the 7000 series machines are all "German." Now that I look at them the 7000s have many details from the 1400s.
It is a pretty machine and does every thing one could ask.
So now the "Stable" looks like this:
Returning to my Automotive references the curvaceous lines of the 60s made way for the hard edged styling of the 80s.
