Thank to all who have replied.

P&P just been cleaning out the waffles with a dremel brass brush.

There is the slightest hint of a pin head in 5 of the waffles. A number 1 in the centre waffle.

Marking around the edge –

Front edge R 2 and Kanji for front. Below 40-1328.

Other edge
1.17OKG

markings below – obliterated except for an S at the end.

Weight ( without) rings -1170-80 g

Definitely from a damaged machine – gudgeon retaining pin still in one groove. Bottom scraper ring edge broken.

But also lots of chisel marks suggesting enthusiastic liberation.

P.S. the RAF cap badge was on a home made wooden circle and painted with Humbrol red- so nothing authentic – apart from the badge.

Mike the chap had a piece of cable from HMS Hood and I saw he had this as well so both are on their way.

Not many pictures of Japanese aicraft engine parts around for a positive i.d.

Thank you Mr. Sabrejet.

I am making the assumption that from the top two numbers in sequence that they are from the same machine type.

If my memory is correct and they are from Silloth it is unlikely to be Meteor being scrapped so soon after the end of the war.

I found them again as my wife is clearing my desk of all its clutter to take to Flying Legends this weekend.

Thanks for all ideas.
