silver palace slot machine

[JHSS-1944]

Hello;
does anyone know if the original Silver Palace badged slot machines were done by the "casino" or, special order from Mills / Bell-o-matic ??
seems to be a few other machines with the same question;
1) bonus bell 1948ish
2) star / sheffler star 1939ish
3) clover bell late 1940's = ?
4) bingo bell = ?
5) criss cross = ? Not the revamps by Buckly.
any help would be nice. Just trying to keep straight what Mills actually made VS. casino "conversions".
thank you.
