After a little research, I would guess that there IS a SVG image somewhere. It is quite possible that this data file (actually .XML text ?) may be available to full members of the MMA for legitimate purposes as part of the organisation's promotional support activities.
I did some checking regarding the SVG image format, and I note that web sites that discuss this show images referred to as being SVG, but what comes through to my computer is actually a PNG. This is reasonable, as I'd guess that the full specification data for a SVG image may be fairly large, and the overhead to scale and display at the user end may be substantial, so the process may well involve the server doing this, creating a scaled PNG file (MUCH smaller data-wise) and sending that through rather than the full vector data.
Maybe TMA will, in due course, explain the availability of their logo data.
