Vinegar is a mild acetic acid…. obviously. When used on iron as a rust remover, it helps to neutralise its after-effects with an alkali…. soda will do.
It looks as if your plane is an earlier model. That plane went through a number of later design iterations before production was abandoned. Originally, the cutter set went down to about 1/4″; the 3/16 and 1/8 blades were added later but it meant that they would not fit between the two stocks, (the combined depths of the two side grooves were wider than the blades) so, when using the two smaller blades, the moving stock was removed and a bolt with a large round head was substituted to clamp the blade sides.
Later planes incorporated a side lever for adjustment which engaged with serrations on the undersides of the blades.

About half way down the page. There’s a pictue of the clamp for narrow blades, plus the chip deflector that nobody ever used…..
Yes, the notched blade is for T&G. The groove is cut with (I think) the 1/4″ cutter. To test it for width, it should be just marginally wider than the gap in the tongue blade. If it fits inside, your T&G won’t slide together.
Good luck
