Needed - Brass Head for a March 809HS 1/25 Pump

I broke the plastic pump head off of my March pump at the threads.  I would like to pick up a Brass replacement.  Anybody know of a good place to pick one up reasonably?  If by chance you have a part number for one, I could then maybe find one on e-bay.

Thanks

I know this is the whole pump with brass head:

I got a replacement head for mine from a dealer your way, but I can’t find the exact site now. But here is a list of the official March pump distributors March Pump Distributors Across the US and World | March Pump
I really wanted a stainless head, but it was $240. That reminds me to buy a lottery ticket.
