The Model Bus Supplement is an optional extra, published quarterly, in March, June, September and December.

It is aimed primarily at those people who operate model bus fleets, and gives news about the fleets operated by MBF members, in a form similar to the widely respected Fleet News in Ian Allan's "Buses".  As and when space permits, feature articles and sales & wanted adverts may be included.

It is A5-size, similar to the Journal, but is non-glossy, black and white, text only (no photos).

A typical example of the content of a Supplement is available here.  Although this has been re-formatted to suit the website, the text is taken straight from Supplement Issue 141 - March 2004, with only the names of the contributors removed to protect their privacy.   Note that this is rather long, so may take a while to load.
