Norm This is a later block it has the vent stacks (2) on the right side. It also has the ninth head bolt (dead center). There is the boss on the right side of the block which will have a serial number.. but they seemed to get carried away stamping these as I have seen the serial number stamped in as many as three places. On the milled head surface, the boss and also the vent/push rod side (which is hidden by a cover).

So block is 1924 or younger..

Bob .. I recall something about the 9th head bolt and can see the center hole in this block. Ah you mean those two vertical rusty posts between one and two cyl, and three and four cyl are vents which are hidden under the push rod cover ? Yes I note the boss on both sides of this block. So this is 1924 - 1926 range. Not of any historical value or use I would imagine now.

I added some more pictures to the Dropbox folder referenced above. One appears to be a date: 4 17 24. No sign of serial numbers on any of the bosses, though that appears to be a moot point. I might list it on ebay for cheap, in case someone local is interested in a relic.

Thanks,
