Section 79E. If any business, institution, member of a profession or calling, or any department or agency of government, in the regular course of business or activity, has kept or recorded any memorandum, writing entry, print, representation or combination thereof of any act, transaction, occurrence or event, and in the regular course of business has caused any or all of the same to be recorded, copied or reproduced by any photographic, photostatic, microfilm, microcard, miniature photographic or other process which accurately reproduces or forms a durable medium for so reproducing the original, the original may be destroyed in the regular course of business unless its preservation is required by law. Such reproduction, when satisfactorily identified, shall be as admissible in evidence as the original itself in any judicial or administrative proceeding whether the original is in existence or not and an enlargement or facsimile of such reproduction shall be likewise admissible in evidence if the original reproduction is in existence and available for inspection under direction of the court. The introduction of a reproduced record, enlargement or facsimile, shall not preclude admission of the original.
