C# determining calling object when external .COM libraries constructors are fixed

I utilize a COM library to receive historical quote data on currencies. My problem is the constructors of the event are fixed.

m_HistoryLookupClass.MinuteReceived += new _IHistoryLookup2Events_MinuteReceivedEventHandler( m_HistoryLookupClass_MinuteReceived);


void m_HistoryLookupClass_MinuteReceived(string bsData)
{
... //send data here
}

since at any given time there may be several instances of m_HistoryLookupClass
running, how can I determine which instance called the minute received event? Normally to accomplish this I would pass a reference to the object with the constructors, but the constructors are fixed by the external .COM library and I can't change them. (or is there a way to?) Any help would be very appreciated, and if I've been unclear please let me know! thanks
