I'll send you a couple.
Typically you want a normally-open momentary SPST switch, like this:

I've started doing that on a few new projects. There's usually not room to mark them on the PCB though. I've put a few labels between lugs, but it's not consistent.
The most recent forum update uses predictive AI to determine if you really like the post you are "liking", or if you're just liking it for street cred...
Performative likes are ignored.
Follow the stripboard.
It'll work either way because there isn't enough DC potential to cause any issues, but technically the positive side of the cap should be facing Q3.
I think it's a legit person, I found posts on another forum going back to 2018....
With that said, I'm not sure this is the best place for assistance but we do have a few STM folks here, so maybe...
The Double Muffin doesn't have the tone bypass circuit.
This doc might be easier to work with (just don't use the drill template):

What do you need? I have a few.
Mouser has these 1/4W resistors in a 1/8W package size, you'll have to find your values.

The first versions had exposed pads under the breadboards that made contact with the power rails. The voltage for each breadboard rail could be set with removeable jumpers, rather needing jumper wires.
The breadboards needed to be tightened down evenly to make contact and it was...
They were originally intended for attaching the breadboards with small screws.
They should line up with mounting holes underneath the adhesive layer on MB-102 breadboards.
