I have a teardrop kit and it has factory stock metal bass drum hoops. This is the way they came.

Ive seen Sonors with metal bass drum hoops...Now are you sure the snare drum is a Sonor? looks like a Trixon to me...better pixs might help!

Thanks for all replies!The drum is sold yesterday.TO ME!I went to pick it up in town about 60 miles from my town,and I bought the shell set 20-12-13-16.The drums are in perfect condition for 40 year old drum.I am only missing two ball shape rubbers for floor tom legs,everything else is there.Got it for about $320 without snare drum.Unfortunately snare drum is ruined and I didn't want it.I was sad because what some of the previous owner did to it.I found it on the some Sonor old catalog scans from 1958.It is D425.You can find it on the pages 44 and 45 of that page,link below.It was originally 14 1/2" in diameter,and during the years some of the owners could not find those heads and they destroyed snare by cutting it and small diameter for little,and did the same thing with hoops,cut,put out a small part and than weld it again,and now is smaller distance between lug 7 and 8.Total disaster,I was so so,so sorry when I see that.I will put some pics in next few days when I totally strip shell down to wrap,remove all lugs and holders.For now,what I can see there are no major scratches in wrap,no cracks at all,and wood is in perfect condition and I think that all of edges are fine.I put some scan from net,my drum is exactly same,with different wrap color of course.

Glad you grabbed Dule.....

Sonor's sure are cool drums!

Great kit,4 drums for an average of 80.00 each?Great price for sure.Are the shells re ring or straight?

Thank you all again.Shells are straight,not re rings,toms are 8mm(5/16"),and bass drum is thinner!7mm(9/32").Tomorrow I will measure depth,because I think they are slight shallower then 8 and 9" for 12 and 13 toms

That is one cool kit guy !!...Are those spur tips blue ?

They look it in the photo on page one !!

I start to dis amble the whole kit,and so far everything is looking very god.No ply separations at all.Depth of toms and bass drum are little less than standard,toms are 12x7 3/4",13x8 1/4" and bass drum is 20x13 3/4".I found stamps on 13 and 16" shells,and they are 002 and 003,so according to Sonor nomenclature it is march and February 1970.When I striped shells,I notice that lugs are same for toms and bass drum.There are no tone controls on drums,no holes,so kit was without tone controls.I put some pics of inside of the shell,and edges,so you can determine the number of plies and shell material.The edges are slightly round to inside and I think 60 degrees to inside

I will keep you posted until I clean and re assemble kit again

Odball.They are black,maybe was reflection and dust on the pics

And some more pics
