The 18-4,895,xxx should be in the 1939 serial number sequence. I'm no expert, and I used a 1950 Motor Manual for a reference on this.
The casting number is usually at the lower back of the case, and is generally unreadable if there is any crud on it. I think the guys are looking for a prefix, such as 48- (1935), 68- (1936), 78- (1937), 81- (1938), 91- (1939), 01- (1940), etc.
There is also the possibility of a 99- (1939 Merc), although I'm not sure if that even exists... just speculation.
