500 series that says 500 C/D CONV

[BDM]

No date. Where the date would go it's printed CONV. I assume that means conversion? Nothing on Paul F's site about this. Any idea?

I did find something on Paul Fassbender's site about the CONV.  Near the bottom of this page under the title: When Was My 500-Type Set Built.
