Thanks Peter, glad your “looks Kosha but a tad too good” with your significant experience conures with my extremely limited knowledge.

Thank very much for advice for screws to check, I am however not 100% sure which is the desiccation screw you are referring too, on the exploded diagram in your book would this be item no. Plate reference 11, screw machine BA steel slot drive no.2 x 0.187 in. lg.

If these screws match diameter and length would it be reasonable to assume this is at lease period built by TH&C?
