assuming this is genuine - I wonder how many swords were actually forged, and more interestingly, how did this one get released into the public domain for (legal) re-sale.?
I imagine that if any were produced it would only have been a small quantity and the QMs department in the 1930's, equipped only with ledgers and quill pens, should have been up to the task of keeping accounts?
It's not like Victorian kit where there was a 60 year + timespan for stuff to go missing FFS!
I think they are likely to have been private purchase.
My parents had two Edward VIII items relating to a Yeomanry Regiment - they were a cigar lighter in the shape of the orb (it rolled around the table but always righted itself with the flame uppermost) and a silver cigar box. Both were bought very cheaply by my great-grandfather at the time. Sadly they were stolen last time the house was broken into.
