BB-H240B-BM.tap.gz <http://www.bitsavers.org/bits/DEC/pdp10/magtape/dec_distribs/TOPS-20/BB-H240B-BM.tap.gz> is one, BB-H241B-BM.tap.gz <http://www.bitsavers.org/bits/DEC/pdp10/magtape/dec_distribs/TOPS-20/BB-H241B-BM.tap.gz> the other.  I'm not sure which is right.  The description file (labels_combined.txt <http://www.bitsavers.org/bits/DEC/pdp10/magtape/dec_distribs/labels_combined.txt>) has them listed as:

BB-H240B-BM         DECNET-20 V2 DIST TAPE                1980     _tops-20
BB-H241B-BM         DECNET-20 2020 V2 DISTRIBUTION        1980     _tops-20
