It is traditionally regarded as correct to use the subjunctive after as if, especially when we know the thing we are supposing is not true (the map isn't ancient).
It was dirty as if it were very ancient.
If it's not certain whether it's true or not (the map may not be old), it's OK to use the normal past tense - as if it was.
