'53 OTS. Fender welt. Who has the proper size?

As I do body work I’d like to be sure of the fit of the welt. I have some on hand that I don’t think is the correct diameter.

Can someone spec the correct cross section and supplier if they have the correct goods?

Thanks.

I used 1/4" diameter, seems to be a universal size, plenty of sources on ebay.
