Does anyone know what the casting # is? My spare sold to me as NOS (who knows, it looks perfect) has # 620954-13 on the under side. I thought there was an old thread here about this somewhere but can"t find it. Thanks.

Additional info- Spare has typed part # taped on with cellophane tape. It says " 2805 00 040 1312 MANIFOLD 1 EA. A-4/75 SM"
Doesn't match my parts book # for "Manifold with w/heat control VALVE assy." Anybody recognize the part #?

Wow that was quick. Thanks to you both!!! I just checked my 212-20P Feb 1960 and the # is the same there. I was looking in ORD 9 SNL G-741 January 1954 which doesn't list FSN #. I bought the spare years ago for short $ hoping the guy had it listed correctly. Always wondered if I was just storing a giant fishing weight.
