Your right Dude in general they don't. The IP in question is a put together. Stock is wrong and should be an I cut, receiver appears to have been polished, a third of the Rock-Ola barrels sent to IP were not delivered till the end of March 1943 and IP was already shut down. The serial number is a 1.76 which would have been used well before March as it is not on an S'G' receiver. My 1.77 has an Underwood 1-43 barrel as an example. Not worth anywhere the price it brought.
