B1 Bogies
Here are files for various British Railways B1 bogies. They are drawn full size but designed if scaled by 1.31% to suit 1/76 models. Most are designed to be direct replacements for Bachmann OO bogies, but can be adapted to suit other projects.
I have drawn a rivetted construction bogie, one with some welded construction and one with internal swing links.
I have also done a detailed cosmetic bogie which could be used as a wagon load or lineside item.
Enjoy
