Reference photography not yet on file

The original. Sold under the Seastar name with PRX as a designation rather than as the model name, which is why period examples are catalogued inconsistently and why the catalog records this as a named reference rather than a numeric one. Its specifications varied across executions and the catalog does not yet hold a reference-level breakdown.

Some specifications for this reference require verification against manufacturer documentation.
