dolos Eish...once upon a time Mighty Mite parts were available and would have been the closest I've seen (AFAIK they were supplied by Cort factories). Bothners were the stockist, but I havn't seen the brand in years and don't know what replaced it.
Right now, I'd probably go for a replacement set of tuners and tremolo arm instead of looking for originals - you might find Cort parts will match or perhaps Wilkinson (the bridge saddles look familar). I know the Gear Junkie have some weird bits in - at least you have a decent chance of finding a trem arm that'll work (matching the thread)
Blackbeards Den &/or Terry Distributors stock new loclally stocked, chinese sourced bits that may work too.
