One vehicle, 2 names:
• Freightliner FS-65
 more precisely:
  ∗ 8 Freightliner FS-65 Thomas;
  ∗ 37 Freightliner FS-65 Thomas Built;
  ∗ 1 Freightliner FS-65 Thomas Saf-T-Liner Conventional;
 There are also
  ∗ 5 Freightliner FS-65 "only", which should be checked by someone to see if with a Thomas body (bus bodies are a little bit off my line of expertise);
  ∗ 4 FS-65 with a Bluebird body, 1 with a Carpenter body and 1 with a Corbeil body, but these 6 buses are not part of the "Freightliner or Thomas" issue and should clearly stay unchanged.

• Thomas Built Saf-T-Liner FS-65
(15 bus identified that way)

Which name should be kept?

If the following detail may help:
- a Freightliner FS-65 is not a complete vehicle, it's just a bus chassis without body;
- the chassis was developed by Freightliner in partnership with Thomas Built;
- when unveiled in June 1996 it had a Thomas body;
- the two first buses that were sold, in January 1997, had a Thomas body;
- if available along with Bluebird, Carpenter and Corbeil bodies from 1997 onwards, the Thomas one remained the last one to be proposed from 2002 until the end of 2006...

Shouldn't we use the Thomas Built Saf-T-Liner FS-65 ID for all buses clearly identified as Thomas versions, and keep the Freightliner FS-65 one only for the non-Thomas bodies, the same way it's done for other bus chassis?
