Can someone tell me what year or year span these Pearl drums were manufactured? They have black wraps with a black and gold "Pearl" logo tacked in the side,. All the shells are painted grey inside and with the exception of the bass drum they all have mufflers installed.

I am looking for a set of bass drum spurs for this kit. Right now we call it the "Lt. Dan" set because it has no legs. :-)

Thank you all for your help.
