FWIW: I have a set of books called "Amateur Telescope Making" which
describes the method of silivering telescope mirrors. The first of the
series has an original copyright date of 1935. I believe that amateur
resilvering was routinely done then. For many years there was a column on
the Scientific American Magazine entitled "Amateur Telescope Making" and the
books were an outgrowth of that column. I believe the column dated back to
before the first publication of the book 1 of the series - perhaps 1932 or
so.
Today, of course, telescope mirrors are aluminum coated.
BTW: telescope (and sextant) mirrors are normally front-surfaced.
