[CR]brake hood ID?

I have a pretty nice old Davidson that I enjoy riding but the brake hoods are deteriorating. These look like aftermarket hoods for the Super Record brakes. I would like to search out a NOS pair to have tucked away but I don't know what I am looking for.

I have put a couple of pictures at http://www.wallbike.com/bill_personal/davidsonhoods.html Can anyone identify these hoods? Does anyone have a set that they don't need any more? Or a source?

Thanks
