Is there a photo on the box or the instructions sheet showing what your completed Tennyson is supposed to look like? If so, would you please post a photo of it so I can see if it is the same as a die-cut ArtPly dollhouse that I constructed in the late 1980s. Although mine seems to be a Tennyson, the kit from which it was built apparently predates that name. That is, I still have the instructions sheet for mine and they entitled just "Dollhouse."
If your dollhouse is the same as mine, I might be able to help you. I am in the process of refurbishing mine, so I am partially dismantling it. If I can get to the pieces on my house that are missing from yours, I might be able to trace mine on paper and send those to you by postal mail.
