    It says that the bridgeport S/N is on the knee. Where on the knee? The only S/N I find is on the head and its 6516 which is OLD (older than I want to believe my mill is)

    On the knee (between the ways) right above the y-axis crank handle. Might have to slide the chip guards back. Should be facing right up at you. The head number is different from the machine number.

    On this side of the pond, the head s/n is not correlated with the machine s/n. The latter is on the knee under the sliding cover plate, directly behind the Y-axis handle. You can't determine age from the head s/n.

    Don't know about the Adcock-Shipley but I expect it's the same.

    Cass,

    As Leigh says, I don't think the machine serial number and the head serial number match. The UK machines have a different number system, but this still seems to apply.

    I have an Adcock-Shipley BP, I know it was supplied around 1974, and its serial number is 187490474 SX (stamped on the lubrication plate).

    I am told (ie on forums) the last four digits refer to the month and year, ie April 1974.

    The head number is quite different: 2JB 5304.

    The parts book states that both these numbers should be quoted when ordering parts.

    I just saved a bridgeport mill base from the scrap yard, it is one I have never seen before. It is ser# hp935 on knee, it does not have dove tail ways the ways are rectangle with chrome. There is also an X axis feed wheel on the X Y base as well as the left and right ends of the table.It is in excellent condition overall.The turret mount appears to be a J style there was also J head head casting inside the base. Does anyone know what this model is and anymore information about it? thanks Craig
