During new testament times copies of the old testament were

were very seldom to found as they were not produced on great scale.

Explanation:

During new testament times copies of the old testament were not produced on great scale, in fact, even though handwriting was already developed, it was only practiced by people with enough status and resources to learn it. Jew priests were the ones in charge on making copies of the old testaments and were only for teaching of the priestly class and not to distribute to other people. It was also possible to find other copies of the old testament that were made by jewish sects, but again, those copies were very few and difficult to find during the new testament times.
