It was a Wilo Star 16, which they discontinued. If you can find one online it will bolt into that body, even if it is a flange version.
We have Grundfos 15-58 replacements. NA10481. is the part number, they come up on a search at most suppliers.
Its a common 15-58 with a 1" union body, so replacement motors are easy to come by.Bob "hot rod" Rohr

Star 16 on ebay, make them an offer
Someone probably sitting on pallets of these?
Nice thing about Wilo, just 2 allan bolts to swap.
Not much $$ more for a Grundfos at SH.Bob "hot rod" Rohr
