> Question: (possibly very naive!!) does Modula-2 allow assignments of records ?

Yes. I couldn't find a direct citation, but I've used the feature on
several compilers.

The answer can probably be inferred from section 9.1 of the Report. It says
"Operand types are said to be assignment compatible, if either they are
compatible or ... " Since any type is compatible with itself (another claim
without a solid citation that I can find) it seems all types can
be assigned values. I've made a table of all of the Modula-2 data types
and their allowable operations.  Assignment is the only universal operation.
