This is a for a Jaguar XK engine front breather. The area that goes against  the head has been surfaced. There is not a stud for the front ignition coil mount so most likely for one of the sedans of the era. Outlet hose size is 7/8".   I do combine shipping.  Click "Buy it Now" and request shipping amount if buying more than one item from my store and I will send an invoice.  Shipping is for the lower 48 USA. If elsewhere, please write for shipping costs.
