Now this is were it can be problematic for any future “new” pressings.
If the original Stampers are not available, for different reasons!!. “New Stampers” can be made from Vinyl pressings not original Lacger or Metal Master.

Back in the 70's there was a good article in one of the Hifi magazines about the process (possibly Hifi For Pleasure). I seem to remember that stampers were normally only good for 10-20000 copies although there was a mention of a Bridge Over Troubled Water stamper that was used for over 100,000 copies.
Not sure about the making new stampers from vinyl pressings idea - even brand new mint condition vinyl has the odd blemish here and there. Nowadays (certainly for the labels I work for) we find the best copies that we can, transfer them to digital and use digital tools to remove as many blemishes as possible. A new laquer is then cut from those digital files.
