I have an Atlas 045 switch which has the small plastic guide for the pick up roller missing, i.e. the triangular wedge that goes between the centre rails where they split. What is the correct name for this part please, and can I buy one? It was a used switch I bought, and didn't come with it. The rollers 'clonk' when passing over the gap. (Image shows the said part on a good switch.)
Thanks,
Tim
