Hi Catherine!
Glad you liked how your brother's snare drum came out! As to the cosmetic issues being an issue with a buyer, I'm leaning more towards yes it will. I've always maintained that "condition is everything". Your Super Sensitive snare drum is now very clean and properly adjusted...and sounds great. There will be a market for this drum, but I'm not sure how much of a monetary hit it will take due to the cosmetics.
I'm hoping more of our members will chime in with their thoughts on what this drum should sell for.
