How would you read this Block number

[Nodakwalleyer]

Hello, any response would be appreciated. I was looking to buy a 1931 engine from a fellow and ask for the Block number, this is what I received. Not sure how to read it but when I looked it up I would say it is a Jan 1928 engine, anybody know what the other markings are? thanks

It's a grind and restamp, so you'll have to look at other features to date the block.

Thanks Tom, appreciate it.

The rebuilder had # stamps but no letter stamps.

In Illinois, an SOS prefix was an indication that the state had issued a new number. It stood for secretary of state.

interesting
i bought an A from ill that was titled with an (((sos------ill))) so when i brought it back to pa i just transfered it and the same number followed to the new title and registration. i am legal it just does not have the original number. i have since restored the car and did locate and write down the original frame number but will leave it as is...
thanks for the info
