Please provide ward maps containing door numbers for bangalore city in 1970. This information is of importance since many old properties use the numbers and subsequent changes in door numbers invalidate the old sale deeds.
for example if the door no was 8 in 1970 and then it is changed to 40 then the sale deed bearing no.8 becomes invalid unless the ward map of 1970 is available to show where no.8 was at that time.
