can't help you with the Bond usage, but I can give you a 14th century use per your citation:

c1374 Chaucer Boeth. ii. pr. iii. 25 (Camb. MS.) The moost presyous kynde of any propinquite or alyaunce þat may ben.

oh, and I did find a net use of "obese propinquity" that was explained to mean "fat chance".
