A great USN fixed bale M-1 Helmet, denim laundry bag and Anarac jacket.   Helmet named to Roberts, J.O, S 1/C  579-xxxxxx, last part unreadable.

My guess is......... 49 tick marks.... 49 weeks...... ?

These pictures were taken when my 7th SFGA, Co D, B-team had cross training around February 1968.  Back then, cameras to take pictures were not a problem.  The first picture shows the regular crimpers/cutters and dynomite.  The block explosives is C-3. which was replaced by C-4.  The second picture shows the sheet explosive Flexl-X.  The third picture shows the M-3 Shape Charge with stand., along with a one-pound block of TNT, and, in the background, a 10-cap blasting machine.  The last two shows the before and after detonating the shape charge.

Sorry, I can't make out the markings.  They appear to be scrubbed.  Perhaps reworked or refurbished?  

Nice 👍    mine will just be used in public displays for basic kinds. Of kit carried by differs eras of GI’s.

Yah, that’s what I was thinking, but wasn’t months more common? Can’t think of any time I’ve seen it week by week. I’m thinking something else not time related, maybe individual patrols he’s been on, I have no clue. This can’t go much further till I figure out his unit and all.  

Here is a small diagram, all of them seem solid, and it doesn’t look like they were trying to be crossed out. If they were being crossed out I would imagine (or at least what J would do) is just scribble lines across the rows.

A wartime machete is one of the things on my bucket list. I wouldn’t mind a nice salty one that I could use around my yard. I like the decoration on the scabbard.  It’s nice to see there are a few things left in your little old shoebox.  mikie

Thank you all, just because of what his aunt said doesn’t mean it’s necessarily true, she has mild dementia and is about 85. I’m surprised she tempered the full name. I am super excited about this helmet. I have no idea how I’ll research it though as I don’t have any subscriptions and the best I can usually get on my own is his time of service. Thank you all for the comments and the little nudge from imagination to reality. I will keep looking at the helmet. This being ID’d is slightly mind blowing, I haven’t had a find like this really ever. I’m the meantime though, I will need to figure out the writing in the back. I will write it down on a nice piece of paper as a diagram so everyone can see it clearly.

I plan on creating a display case for items associated with the Engineers and the cutters will be displayed there as well.
