I have similar to that in my Swallow, it looks like it is Wilmot Breeden, what has broken, these are very simple (and cheaply made when new), they turn up every now & then - I know of two sizes, a larger one with hole centres at approximately 1.3/4" and the smaller one has hole centres at just under 1.1/4", I have a spare smaller one.
