pinkcastle, pinkCastleDH,
Those are some pretty neat finds.
There is absolutely NO reason on this earth to part out that 66-4. It's complete, it's in good condition cosmetically, (I've refurb'd worse) and I'll bet that machine sews beautifully. Get out the oil and cotton balls and clean it up, then oil it and use it.
Part it out ......... BAH!
The Viking? It's a neat machine, but I now nothing about it.
