Check with Remo you can get heads for the drum.The drum is a metric head size very common with vintage english made drums..Mikey

I measured the shell properly and it doesnt fit the remo metric heads either. Im at a loss now really

Remo can make heads for you but they are expensive. There may be some old Everplay or HeadMaster heads around , that will work on that drum. The pre-1964 Trixon drums were 500mm, which is just slightly larger than that. The flesh hoops from one of those , might allow you to put calf on. I'm assuming you didn't get any flesh hoops with it?

What are flesh hoops?

Actually if flesh hoops are the thin wooden hoops that came with the normal black ones then yes i got them

That is correct. You can have skin heads( calf or goat or other) , put onto those. There are a few people around doing this but there is some excellent info. on this forum about tucking a calf head. That might be your best way to go.

Thanks heaps :) . however this opens up a new set of problems because I am in Australia and its gonna be either very hard or very costly to get a real calfskin

There is a big cult here in Canada for making your own Jembe, or whatever. There are a lot of shops dedicated to supplying raw materials. They import Goat and Cow from Africa, Pakistan, other places. There are probably shops like that in Oz? I've done goat for a bass drum----you can get a suitable sized piece from a big goat. Any Roo skins around?----not sure what that would be like. Sheep is no good but I've done Deer and Bear.

Ill have to look into it a bit more. Thanks again for your help calfskin
