Can't find where this sucker came from. Ser. # 440-20730 nothing on the water pump housing. No skid plate on the oil pan and it has the old school riveted oil pan nut. Cast # is 5-2 636953 W1 N1 CR N2. It's an L-head for sure looks to predate my 638632. The head on it is bolted on, not studs and nuts.
So I noticed somebody was collecting L-head numbers here's the rest of the family
The one I assume is from my MB is
cast #3-8 638632 W1A N1 CR N2
she has a gear set timing cover the tag on the block serial MB-569519
water pump has a 2 on it
then there cast #804380 W12 DP5 CU CR
No serial tag number
water pump is 4LR137253 B
Last one in the '46
Cast# 3-22 641087 LW10A CR-N
No serial tag stamp
water pump IT68471
I'll list the heads here in a new thread in a minute.
