The snare is aluminium (I'm trying to upload more pictures but it's not going very well..) And yes it has 10 lugs. She did tell me it was "custom made" so maybe it's a special order? Also I looked inside and it doesn't have any special markings. There is a sort of damaged area that's circle shaped so it's possible something has been there earlier.
Also I found an old paper with the bands birth dates and most of them seem to be from the early 50's or late 40's. Not that that hinders them to buy something older then a kit from the 70's but still it's maybe more likely that he bought it in his 40's or later and I don't think he bought it second hand at least.
The kit is in wood for sure but it seems the floor toms (Tom 3 and 4) are painted or coated in something grey'ish.
As I totally fail at adding attachments I'll just post the links here and maybe a nice admin can add them to the first post. XD ..
