Can anyone help? I’m looking for old, damaged or beaten-up Binson Echorec drums so that I can undertake a close and thorough examination of them. This will include making accurate measurements of dimensions and taking close-up photographs (possibly electron micrographs) as part of an ongoing project to create accurate engineering drawings, parts lists and document and preserve knowledge on these fabulous old delay-echo machines. My main interest is in determining the authentic construction techniques used at the Binson factory in the 1960s for winding and refacing the drum. Another useful spin-off from all this research effort is that it will aid those who wish to restore worn or damaged drums, so be assured this is all for a very good cause. If you can help in any way then please contact Phil. Any help would be greatly appreciated. Thankyou.
