it has been a long time since I picked up a pith, but I swapped some items for this one today at a fair local to me.
Very good condition with a WD arrow and date letter P for 1941 with the foil lined dome. It appears to have been an OR's pith which has been upgraded to Officers version with the rim trim changed from cloth to leather. You can see the old stitching holes from the old trim and of course Officers would be private purchase and should not have WD issue stamps on them.
It also has his names/initials on the chinstrap. It is nice to see it still has the chinstrap as they are often missing. It also appears to have 101 in white paint on the rear brim.
