My guess is that it's a custom made kit from the 90s.

The absence of vent holes is intriguing.

How does it sound?

The lugs look like some older MIJ to me.

To my disbelief it sounds amazing. Very tight punchy sound. I may have to experiment with some vent less shells myself on my next build. I never have tested the theory. So why not lol.

OMG amazing! Before pics? I'd love to see them.

I keep trying to upload the before pics but it won't upload. I will work on it and get them up. It was in really rough shape. I build and restore drums for a living and I must say this was on of the roughest ones to bring back to life yet. Although customers keep me on my toes.LoLoLoLo

Beautifully done!!

Is that a BumWrap design?

Why yes it is. They are my new #1 go to supplier, Best service I have had, and any options I want or can think of. Not to mention the quality. Working on another kit now that will be sure to amaze. I was very apprehensive at first, but they proved themselves to me.

Before the Restoration. Lugs were in a old bucket

Wow, their online samples don't compare to what it looks like, full size, on a kit. Very nice!

May I ask whether you used glue or tape, or a combination of the two?

I always use glue unless the customer is wrapping them to protect the original finish. Then its just tape with the wrap adhering to itself, Which works great. These were in fact glued.
