Vintage Coburn sliding door fittings
 

I am looking for some vintage Coburn sliding door fittings for my shed. I have all the tracks in place and the doors have been hung on my garage for 23 years. I think they were hung up in the shed of Watts of Beverley for at least 60 years prior to me obtaining them.
I am in need of 2 off 2 wheel end hangers. The wheels are 3" diameter and the overall width across the pair of wheels is about 1 3/8", each wheel being about 1/4" wide. The track and width of the wheels is important but if you have something with wheels of smaller diameter I am sure that would work. I am also searching for some of the guides that attach to the bottom of the doors and run in the floor channels.
Any help would be much appreciated.

All parts still available new .

Thank you for your reply. I have seen the Coburn website and the sizes of channel and fixings are different to my old ones but I will check with Coburns after the weekend to see if they do replacement parts for obsolete systems.
