I recently acquired a batch of flathead blocks, 3 of which are stamped on the bellhousing in raised letters "59", "69" and "79" respectively. On my reading of earlier forum threads I believe the "9" signifies 239c.i. and I thought the 5,6,7 represented the post WW11 war years. Am I correct in these assumptions? Thanks David
