I believe this is for the OHV rocker boxes for the 600cc and 500cc saddle tank Sunbeam models between 1932 and 1935. Please use the dimensions provided as you guide. If it’s convenient, you are always welcome to bring your engine cases to make sure that this fits before you buy.

Condition: Decent. Considering this is around 90 years old.

It’s clean. The cover decent and hasn’t suffered from corrosion. The external appearance is nice. I’d happily fit it, but I have sold my Model 9 and have no need for a spare.

I am selling a load of small parts for pre-1935 Marston Sunbeams. The parts will all be listed on here.

The price that you see on my advert is for the item and not the item plus whatever taxes might be due.
