Lakeside Manor kit from S/W Crafts.

I don't have any info to offer, but I really like the look of this one. Great find!

This is another one I have never come across. I love it, too . . . these two houses are just fabulous! Congratulations on a really great find!

This looks similar to the LeeWard's Prairie something House. It was made of OSB and heavy as a rock, though.

What is OSB? The boxes for these are really heavy!!

Back in the day, when I first started building dollhouses, S/W Crafts produced nice kits. I did one, a small one, and was very impressed with the quality. This was back in the 1970's, early 1980's. Nice kits..you are lucky to have found one. I haven't seen one for ages!
