Post-War Webley Senior with slim Pre-War trigger?

[45flint]

I just bought an example of this but it has not arrived. I assume this was Webley using the Pre-War triggers up before they changed to the larger “crescent”? trigger? Interesting I see no example of this in the Bruce book nor in the Vintage Gallery. Curious how common they are? It has the longer barrel knurling and the unmarked rear plug. Has to be a 1940’s Pistol? Been looking for a slant grip Senior for my collection, was really trying for a Stoeger Pre-War but I couldn’t resist this one, given that it appeared to be excellent condition. Love the older style trigger matching my Straight Grip Senior.
