Thicker velum of 0.4 or 0.7 mm (.010 - >.030") is fairly common for harpsichord soundboard rosettes, but it >is too stiff for use in action parts. Baumgärtel supply it in 0.3mm and 0.7mm. They advertise the 0.7 for Blüthner damper bodies and I haven't got one accessible at the moment but I think the 0.3 would be the proper thickness for this and is what I used on the last set I did last year. I have also located a supplier on eBay for morocco-type leather, very reasonably priced, used for the wing-type hinge on Kirkman (as below) dampers etc. Let me know if your interested and I'll look up the id.
