Can anyone else see what looks like a 3 between the 1 & 8 and possibly the remnants of the top loop of an 8 or 9 with the 1 in 186 stamped over it.
Or maybe I should go see my optometrist.

There is something wrong with the "6" and "X"...and I can see the "3" you are talking about.There is an image to the right of the last "0" as well or I need an eye doctor too.The "1" in the 186 is too far away from the next number.(8) .IMHO.

One thing i notice from the pic is that the machined area that the numbers are punched into has not taken to much material off. If you look, it seems that the bosses that extend out are still raw castings, and not machined. Most of the engine number pads seem to always machine these flat as well.
It would be great to see a few more pics of the this, and the actual number from a few more angles to compare to the other pics in the thread in the ebay section.

The font of some of the numbers/ letters look odd but the rusty pad surface looks to be the original machining.
From my experience the pad surface was originally milled using a slab mill cutter, it looks like someone has cleaned up the rusty surface with a flat mill saw file, this leaves those diagonal lines.
Also it's not unusual to find the pad surface not completely machine at the bolt lugs ends. It's not possible to file the surface,clean off rust and still not touch the unmachined casting surface near lugs.....so to me this appears to be original stampings

The block could have easily been stamped by GMH. You should see how rough the VIN plate is stamped on my very early GTS327. But it could easily be a dodgy done later. Look at this wonderful, original GMH stamping. The Canadians stamped their bit in the middle (normally it's further over), so the Pagewood workers did the best they could!

You could etch test it to be certain?
Even a magnetic particle test might reveal more.

GMH may have been the culprits. I've seen a HT GTS350 engine stamped as 308M instead of 350M, and seen numbers overstamped. If GMH machined a 186S block's engine number to stamp X1010 it will show what was there before. To me the 186 and the end 0 even look original. Just the X101 looks odd, especially the X.

The 1's were always stamped more prominent than the numbers, especially on Brisbane delivered cars and in some cases especially with numbers with many 1's in them the stamped numbers and letters were all over the shop.
I do not know why, but that is how they are in general in many genuine numbers. The original stamp kits also were manufactured that only one letter or number could be stamped at a time as the shafts on the stamps were wider than the specific distances between the letters. I have seen some genuine roughies over the years, but this one if genuine takes the cake as the X does not look like anyother X I have seen. Also the cast date on the block seems wrong to that number and if someone can find that engine number on the vin disk and verify that the cast date is where it should be then that would make it more acurate. As I read that cast date it reads as 18th of December 1969.
