Saving Old Seagulls

I realise there is a comprehensive list of nuts and bolts sizes etc on site. I may have missed what I’m enquiring about.

I’m re assembling my forty plus after completing restoration. Stupid me lost one of the two brass nuts that fix the propeller shaft housing to the engine block. After a lot of robust language, nearly pulling my Workshop apart it’s gone.

Would some kind sole tell me the correct size, I am presuming a Whitworth thread. Is it a qtr inch brass?

Many thanks

It would help whoever answers your question if we knew which model & exactly which nuts you want (photo & serial number).

5/16 BSF, if I recall.

Thanks Oyster will do.

To Charles, in my submissive I mentioned my Forty Plus. That’s the model!

Charles, I’ve tried to upload a picture of my machine now fully refurbished but not sure how to do it on this site. What’s your advice.

Thanks
