54 heater box

can someone id this heater box it is dated 12-54 Harrison it was in the trunk of a 52 Chevy i recently parted.
could it be for a 54 Chevy or 55? maybe someone could use it before it goes to the scrap pile.

 

The heater is currently out of my 54' Bel Air, and it doesn't look like your photos. By the date 12 54 thinking it would be a 55' unit. Keeping it inline...Dyno Dave

 

ok i did some googaling and looks like 55 Chevy is the winner thanks time to send piggy to market.
