HELP ! Sorting out military info on Engineer's grave marker (served in Guam)

[Robersabel]

Hi! I'm new to the forum. My grandfather died when I was 4, and my mom and I know very little about his service in the Corps of Engineers.

 

I have written for his service records and think they were in the big batch that burned.

 

Here's what I know, and I am hoping someone can help me decipher what's on his grave marker. And, if I'm really fortunate, someone may have served with him:

 

on his grave: 2751 Engr

HV Shop Co (I assume "heavy shop company?)

 

Name: Charles H. Jackson

born in Mississippi in 1918

Pvt

Enlisted May 1944 at Camp Shelby Mississippi

Served on Guam

Solomon Islands has been mentioned

 

Thanks,

Jenny
