yes that's the one - free westinghouse. so that wasn't a 15 clone? I didn't realize there were US companies copying the 15 as well. learn something new every day!
i just bought a pink atlas and think she told me it was also US not japanese..haven't researched it yet but I love it! sews beautifully and sounds so quiet yet powerful!
I would also likely buy the cool looking machines if they're left-homing just because they look neat but I know their use would be even more limited since I mostly piece/quilt though I could probably branch out into other sewing. I DO like doing the occasional easy apron pattern
looking for L C R makes sense..I haven't noticed it on any I've looked at lately though but I've just now sorta started looking at zigzags after realizing my herd has a lot of straight stitch machines
though with quilting that's almost all I use except for the occasional applique or decorative stitch for a pillowcase or apron...
