John Lindell Spaulding Bat Info.
 

I was wondering if anyone could date these bats for me. I found a collection of old bats in a storage locker I purchased some time ago and this is two of them.
The first says John Harlan Lindell "Collegiate" by Spalding with the number 1623 under it.I looked online and although I did find one example of this bat, I couldnt find any information out about its date. Anyone have any information, it would be appreciated.

The second says "Special Safe Hit Hank Sauer Model" Hillerich & Bradsby Co. No. DC 3.

Both are late 40's to early 50's.
