Here is close ups.
There is no hook, because that is some aftermarket barrel - I would like it to look as carbine original as possible.
rebluing the entire gun would likely make it look no worse than it is?
----------
NOTE - that the action was funny, not stiff, but almost no spring action, so, took out that spring and put in another I got off of ebay (turns out i have 4 other 1900 springs
) - working much better, but if I switch to 9mm, it would need a welded on leaf?
