I have two strange size windows--and yes, I'm sure it's authentic Lego, they say it in the proper font on the pegs. They are both 1x4x5 white. I've looked in the list of parts here and elsewhere but there is nothing. There are two holes each top and bottom between the outer pegs. I hope to find replacement window glass, as neither has them. The white is the 'newer' white. Does anyone have these, or can recommend a site that has a list of more obscure parts? Thanks!
