That's a nice Navy Victory. The SN would date its shipment to about February 1943. Incidentally, I have that one's SN on my SN list. Did you make a previous posting here about it?
Most military Victories chambered in in .38 Special went to the Navy. Those built under Navy contracts had SNs up to about V267xxx, thereafter, those designated for Navy use were procured under Army contracts and had the more generic United States Property or U. S. Property topstrap stampings. Even though the Navy-marked Victories are not that unusual or rare (around 70,000-80,000 were made), they do have considerable collector interest and command a price premium if original, as yours appears to be.
The little symbol ahead of the V on the grip is called the Ordnance Flaming Bomb. It's an acceptance stamping.
Navy-marked Victories are generally worthwhile enough to justify getting a factory letter ($50).
