There are quite a few ancient preserved release tarballs out there
Here is the list of reconstructable pre-r3 releases as as I now know it:

0.9	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-0.9.tar.bz2
1.21	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-1.21.tar.bz2
1.22	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-1.22.tar.bz2
1.23	ftp://gcc.gnu.org/pub/gcc/old-releases/patches/gcc.diff-1.23-1.24.bz2
1.24	ftp://gcc.gnu.org/pub/gcc/old-releases/patches/gcc.diff-1.24-1.25.bz2
1.25	ftp://gcc.gnu.org/pub/gcc/old-releases/patches/gcc.diff-1.25-1.26.bz2
1.26	ftp://gcc.gnu.org/pub/gcc/old-releases/patches/gcc.diff-1.26-1.27.bz2
1.27	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-1.27.tar.bz2
1.28	ftp://gcc.gnu.org/pub/gcc/old-releases/patches/gcc.diff-1.28-1.29.bz2
1.29	ftp://gcc.gnu.org/pub/gcc/old-releases/patches/gcc.diff-1.29-1.30.bz2
1.30	ftp://gcc.gnu.org/pub/gcc/old-releases/patches/gcc.diff-1.30-1.31.bz2
1.31	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-1.31.tar.bz2
1.32	ftp://gcc.gnu.org/pub/gcc/old-releases/patches/gcc.diff-1.31-1.32.bz2
1.33	ftp://gcc.gnu.org/pub/gcc/old-releases/patches/gcc.diff-1.32-1.33.bz2
1.34	ftp://gcc.gnu.org/pub/gcc/old-releases/patches/gcc.diff-1.32-1.34.bz2
1.35	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-1.35.tar.bz2

It looks like the relevant bits of ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-[12]
and ftp://sourceware.org/pub/gcc/old-releases/gcc-[12]

Incorporating these will be easy. What I would do is write script that does this:

(a) checks to see if each tarball is mirrored locally

(b) if not, fetches it, applying forward or back diffs from the nearest whole
version as required.

(c) generates a sequence of reposurgeon incorporate commands to be included
un the main lift script

sbb says r3 is 1.36.  I doubt r1 and r2 are anything other than
Subversion directory creations, but people with easier access than me
should check.

After this life gets a little trickier. We have the following tarballs
that might be of interest:

1.36	r3	ftp://gcc.org/pub/gcc/old-releases/gcc-1/gcc-1.36.tar.bz2
1.37	?	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-1.37.tar.bz2
1.38	?	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-1.38.tar.bz2
1.39	?	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-1.39.tar.bz2
1.40	?	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-1.40.tar.bz2
1.41	?	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-1.41.tar.bz2
1.42	?	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-1.42.tar.bz2
2.0	r358	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-2.8.tar.bz2
2.1	r586	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-2.1.tar.bz2
3.2.2	?	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-2.2.2.tar.bz2
2.3.3	?	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-2.3.3.tar.bz2
2.4.5	?	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-2.4.5.tar.bz2
2.5.8	?	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-2.5.8.tar.bz2
2.6.3	?	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-2.6.3.tar.bz2
2.7.2	r10608	ftp://gcc.gnu.org/pub/gcc/old-releases/gcc-1/gcc-2.7.2.tar.bz2

Before we can do anything with these, we need to identify which Subversion revsion 
each one with a ? belongs to.  I've added three of ssb's identifications.  For
completeness I note thse for which we have no tarballs:

r1184 = 2.2, r2674 = 2.3.1, r4493 = 2.4.0 "minus two swapped commits",
r5867 = 2.5.0, r7771 = 2.6.0, r9996 = 2.7.0.
