This is an old piece, you best take the spring out of the barrel and measure its dimensions.

I am afraid finding a genuine one will be difficult if not impossible,  As joe remarked best to remove the spring and take measurements then consult the GR listings on Cousins uk and watchguy mainsprings and get the closest to the original one.  Mearure length,   width    thickness and the internal size of the barrel.   The general rule is the spring takes uo 1/3rd of the barrel free space 1/3rd arbour etc the final 1/3rd.  By Generale Resorts we mean Generic springs.

the measurements i got are:

2.2mm tall

0.2mm thick

~545mm long

only match i got was the gr6278, which is no longer available. is there anywhere else I could look, eBay isn't pulling up any results.

Give or take 30 mm or so,  will work.

Adjusted in five positions, its a good grade movement. 

Good luck
