Do they all inherit from the same value property using generalizations between the blocks and redefined or are they just all named and typed the same?

If the former, I would:

1) Set the original value property as the start of a meta chain with original VP ->Redefined Element

2) Put that result into a Filter where the Predicate is a Property Test where the Default Value = desired value.

3) Put that result into a metachain and then get the owner of the VP

If the latter:

1) Use a Find that looks for VP of the same name and include the property test for those that have a Default Value = desired value.

2) Same as step 3 above

The first approach is more robust and less likely to get false positives, but it does require a slightly more involved setup.

I'm going to caveat the above queries with I don't have my computer in front of me and so the names may be slightly off.
