Thank -you John for lending a hand. Overall length 6"625, large gear 3".144 thousands/inch. medium gear 2".755 thousands/inch small gear 2"181 thousands /in. The bore diameter is 8.680 thousands /inch .Because I used a vernier and not a micrometer I may be out on my readings . John

From the picture - It can't be from a TD/TF box. The teeth are the wrong way round?

see ebay #121219887490. Visually flip the picture around, and it is reversed from the drawing but matches John's gear. George

George,

I did that and it is still the wrong way round.

This is the TD/TF cluster as listed. With the teeth going from low to high Left to right in the image.
Can't see why the seller would mirror the image? If that was done.

John's cluster is the reverse of this and the writing is the right way round in his image - so it should not have been reversed or mirrored either.

It is very similar but not from a TD/TF as it is shown.

Could it be from another mark of MG? Or Morris maybe?

Thank-you gentlemen for your input. It appears that this gear cluster is M.G.A or early M.G.B models . John

I flipped the ebay picture around- see below. It now matches John's, but still can't tell w/o measuring, counting teeth, etc.

But, if you look at the background of John's image you'll see that the continents are in the right order. Doesn't look as if the image is reversed. Bud

I thought the drawing had the teeth backwards, not John's picture. Upon further review, flipping a photo of a gear in photoshop is not the same as actually flipping it in reality, so not from a T-series. George
