Thank Nicko,

I should explain that the piece we’ve got came as part of a donation of parts years ago. Some of them were sectioned for display/tuition purposes and others were not, the sectioned ones had tags on them, all in the same handwriting, describing the function of the part and the aircraft type it was from the non-sectioned parts had no tags and this is one of those.

We had a pair of identical fuel pumps one sectioned and one not which were from the Goblin 3 and a segment of those is a scaled up version of mystery piece. I’d found that Jetartaviationshop link and that’s caused me to think we’re talking Canberra and Avon for our item and your second link pretty much nails it that ours is an early version of said same.

Now I just need find somebody who has the parts book for the model Avon fitted to our Canberra B(I)12’s or T.13’s and hopefully that will give an exact illustration as it may well be that in our collection of parts some of the other pieces lurk!

Thanks for your help.
