To me it looks like two numbers. 40 is larger than the 2 and the 2 is the same size as months. Could she have been writing that someone turns 40 in 2 months? If written in Oct. 1986, she could be referring to Rosemary T. She could have been talking to an identity broker who said the mother of a deceased child will turn 40 in 2 months, to see if the age of the mother would be plausible for FLEK. She later wrote an entire page on the age progression of her assumed parents.
