Bevel angle on a plough plane

Howdy LJ.

Question for the masses if someone has a moment. Recently acquired a record 043 plane. Only.came with the 1/4” iron. The bevel on that iron looks a lot low to me. I can’t find any references on the internet for the 043 as to what the iron bevel should be from the factory. Does anyone know what the angle should be or have a reference I can go hunt myself?

Thanks for reading and any help you care to share.

Very respectfully, – Abe
