I can confirm that the relevant .rbf files are the same between what I 
just downloaded via "build-gnuradio firmware", and what was
  shipped with Gnu Radio 3.2.2:

Gnu Radio 3.2.2:

MD5SUM                             FILE
================================
7744fe9a8fa7b3009d16789fb5309ae8   std_2rxhb_2tx.rbf
953d288b23adbfcc92e6408131480331   std_4rx_0tx.rbf

Fetched via build-gnuradio, installed in /usr/local/share/uhd/images 
mere moments ago:

MD5SUM                             FILE
=====================================================
7744fe9a8fa7b3009d16789fb5309ae8   usrp1_fpga.rbf
953d288b23adbfcc92e6408131480331   usrp1_fpga_4rx.rbf


The *filenames* are different, but the images are the same.

Pretty sure it's the same story for the .ihx file that is the USRP1 
firmware for the on-board FX2, although it *may* have been recompiled
  under a newer SDCC since Gnu Radio 3.2.2, not sure--in which case, 
the .IHX files would almost certainly be different.

When the UHD interface for USRP1 was put together, it was decided not to 
make any changes to the platform itself, but rather to have
  UHD make the existing interface "work" with UHD, and certain UHD 
features are "emulated" for USRP1.
