Help identifying heat exchanger brand...see pics

[drdray]

I removed this HE off my 1991 Volvo Penta 570. I need to order top and bottom gaskets because I am overhauling it but I don't know what brand or model it is? 4 inch dia. No#'s anywhere you can see there se to label on top end but its gone. The top cap had 2 gaskets under it where bottom only had one?? Any help would be much appreciated.

Bein' a flat gasket, you could cut yer own outa bits of flat rubber gasket material, which can be found at most any Hvac supply house,....
