House number maps - 1890's

Anyone know if it is possible to locate town maps with the house numbers on them? I'm looking at LDS film for marriages in Stupava, Slovakia for the 1800's. Sometimes the house number is listed. I made the dumb assumption that houses would be in sequence. But the FHC volunteer said no. House numbers were assigned as the houses were built. That makes sense. So where would I get a map? Anyone seen one?

Thanks
