Gruen Authority

Has anyonw ever come across a caliber 103 movement? This is the first time I have seen one.
The 1926 Supplement B Parts Catalog shows it, it is 8 ligne (althought actually I measure 7.85 ligne), the catalog says 15 and 16 jewels, but it actally is 17 jewels 4 Adjustments. Mikes book lists it as introdcued 1917 which is well possible. Numbers only for jewels /adj, no jewel or adjustment count in words.
Marked Gruen W. Co., so it may be a in house movement? It appears to be very light weight, almost as it were made of aluminium.
