When I took the trigger assembly off this piece of metal(see photos) fell out on the table. What a way to start refurbishing an old 99M1 rifle!!

Can someone tell what part this piece is off of? Looking down into the receiver I see no jagged part and the parts look clean, no rust, etc.

I guess if I can learn to dissemble the receiver housing the broken part will reveal itself, but without some instructions I am a bit overwhelmed. Never attempted such before. Boy those screw heads are small!

Any guidance is much appreciated!

It looks like a rudder for a Ducks butt! Squirrelhunter said he lost one last year. Seriously I'm afraid I can't help you. Have you scoured social media etc to see if you can find a schematic to help you out?

Hammer

Discovered that the piece is off of the hammer. Anyone have an idea on why
/what broke the hammer?

However, excited on the eventual outcome.

Cleaned and waxed the stock, no need to refinish it. Everything else looks OK.

It may have been caused by improper heat treat, bad forging, etc. Is there any sign that it was dropped?

Drop

No sign that rifle was ever dropped.

Now I discover that the hammer will not cock as shown in Arrowdodgers videos.

But, it will work out somehow!

Hows your project going on your 99M1?

I should recognize it ,if it’s part of a m60 hammer,but I can’t see it as a hammer and it looks like the hammer is in place in the action photo,if ,it’s a broken piece and the two pieces were side by side ? Maybe then? I’ve had many Marlin 60 series actions apart and it does not look like a hammer or part of a hammer,
after looking at some pics I can at last see it as a hammer the old ,long style,and pretty beat up seems to be son file marks on it maybe it was worked on .
