Hullo Gene (moan...)
I've just had a second look....
OF COURSE it's possible...
It's difficult to be definite because some things change more slowly than than others.
Analyzing it logically:
Aluminium wasn't available for general use until 1930s.
Early general use was from scrap metal.
In indo Al wasn't popular until the 1950s.
Here is where I may be wrong:
Three-pinned scales were generally used until the early 1970s, when it was replaced by two-pinned scales.
But, I have never seen that style of handle before H. Aas made them.
Three salient points:
Unusual for TWO hanging rings on the collar and no belt-clasp.
Unusual to cap the pommel.
Unusual crimping(?) pattern on panel above collar.
Conclusion:
It may have been made by his predecessor.
It may have been a custom order.
Best,
