MG MG Y Type - Oil Pan

This oil pan came with a box of TD and MMM parts. It is the same size as the early TC & TD. I think it is a Y type. Is this correct and does it have any value? I'm in the USA so not a lot of Y Types around. Thanks Gary

Doesn't look like any of the sumps on any of my Ys here (YA, Y/T and 2 YBs) as they all have a casting forward of the dipstick for the clutch return spring attachment. There is also a protrusion rearward of the dipstick on Y sumps with a cast brace either side.

No idea what this is off :(

The top one is a TC & TD. It must be from the same Engine family. Thank you Paul for your response.

Could it be from a TC? Most or all (?) of these were right-hand steering so, to Paul's point, the clutch release mechanism would have been mounted on the right-hand side of the casting.

Hi Gary
I am pretty sure it is from a pre WW2 Morris 10. The post WW2 Morris sump was much squarer. The TC and Y sumps were squarer too, like the post WW2 Morris sumps except the TC had a finned bottom and the Y had lugs on the sides for the clutch idler mechanism.
I had a complete engine from a pre WW2 Morris 10 in my shed until I sold it about four weeks ago and the sump looked very much like the one in the photo. See attached image. I still have a post WW2 Morris sump in my shed.
Incidentally, being pre WW2 the Morris engine had no timing chain tensioner, similar to the TB engine (but about 1100cc). If you have that sump, you might have other pre-war bits. Check the head for clearly cast dates such as "1 June 1938". Also check the block and timing chain cover for evidence of the tensioner. Also note the head in the image does not have the rectangular drain for oil. Oil all has to go down the pushrod holes. Pre-war stuff can be quite valuable to builders of pre-war specials etc.

Hi Gary,
An image of the clear 1939 date on a TB head. It doesn't show in this image but this head does have the oil drain which assists the pushrod holes to drain. That was an addition before the war.
