This is an example of a first pattern shovel M43 shovel cover with the fixed hook on the back. Marked HINSON MFG CO. 1943
These were issued with the M1943 entrenching tool which was a copy of the German klappspaten, and itself far superior to the WWI M1910 shovels still in use at the start of the war.
1 only. Example in picture is the one you'll receive.
See this link for the entrenching too which goes in it
