Problem/Question: The BLR-1C BattleMaster is mentioned in canon but does not show up in the MUL.
Explicitly named the BLR-1C twice, it features in the novel Heir to the Dragon as Theodore Kurita's ComStar-supplied command 'Mech in chapters 52 and 65, FASA edition pp. 251-251 & 306-311= Roc edition pp. 287-289 & 346-351.
It is explicitly said this 'Mech came unmodified and without downgrades, i.e. the one in the novel is a factory model in original configuration. In battle it is described to use one (implicitly single) arm-mounted Donal PPC, a Holly SRM-6 launcher, DHS, paired rear-defense lasers, and it explicitly does not have machine guns.
The BLR-2C may have been meant to be this 'Mech, but it bears a wrong alphanumerical designation (and its AMS and BAP aren't mentioned in the novel).
There is a BLR-1Gc variant with a "double cockpit" mentioned in TRO:3075 that seems to be identical to the BLR-1C as described in the novel, and Sarna posits these may be the same model.
Any new insights? I was looking for the BLR-1C's intro date for a story when I found this problem.
