I went to replace the brushes on my 3115 from my Merchant set and noticed someone had used cotter pins to hold the brushes and springs in place and soldered the wire to the cotter pin. I thought it was weird until I looked at another 3115 project motor I have and it has the same exact setup. I've switched out brushes in 15-20 Flyer O and Wide gauge motors and these are the first two examples I've seen of this, has anyone else seen this before? Is this normal?
