[oletrucks] model numbers

[BerOPFL@aol.com]

I'm new to this and reading various model numbers for early 50's trucks.  
What do they mean?  A 3105 must be a panel?  A 3104 (what I have) is a 1/2 
ton?  Does that also designate 5-window (what I have)?  Does it designate 
engine size?  Any clarification will be much appreciated.  Thanks.

Really enjoy the mail traffic and help all of you give one another.  Miq is 
doing a great job.  Thanks.
