Access to Custom Object RecordType Field via SOAP

[pbsdevl]

Is it possible to access the RecordType field in a custom object through a SOAP call?

We have custom objects with Record Type fields.

A SOAP call to describeSObject passing the custom object returns all standard and custom fields except the Record Type field.

The same call passing a standard object returns a RecordTypeId field in the list of fields.

An attempt to make a SOAP query call to select RecordType or RecordTypeId fails.
