Lot of over 30 buildings.  There are one or two that are not International Resourcing Services brand, but fit in okay.  I also saw one building with a chipped roof (see last picture).  The other buildings all appear to be in good condition, I did not see any other notable flaws, but may have overlooked some minor defects.

They are from the early 1990's.

See pictures for details.

Thanks.
