Help Identify this March Pump

[Cioffi]

I'm trying to identify a March pump that I have. From everything I can tell, it looks like an 809 model. I have an 809 model for high temps, food grade, etc., and it looks almost identical. I did a search online but didn't come with anything definitive. I've included several photos. Any help? I sent a PM to Walter from March pumps, too.

Thanks,
Todd

I would contact March and ask them which product the serial number was assigned to.
