Searching for 30U eng. block U235121 to U238023

[30 Ply 30U]

I am looking for a 1930 30-U engine block, or complete engine, with a block number between U235121 and U238023.
As close to U235278 as I can come up with. Anywhere in the US, I travel a lot and can pick it up. Can trade you U209508 if needed.
If you have one of these or know where one may be avaliable please contact me at 765-413-8529 or by e-mail.

P.D.
