I have just replaced the hammer spring on my Kral with one bought from Bagnall and Kirkwood which has similar measurements but has thicker wire and when fitted gave a silly high power so I cut it down to get it under and this only served to give a big power curve. I have done a Google and can only find the narrow one (8mm) whereas I need the 12.5mm wide one. Does anyone know where these can be bought from please.
Many thanks,
Gary.
