No idea! they aren't on the one I inherited from the old pot. Apart from the fact they don't feel all that friendly in the hand (no wood anywhere!), and that cheap-looking locking key, they are a very useable & practical bevel. The blade locking mechanism works extremely well.
Cheers,

The holes may indicate that silex bevel was used to mark out repeated cuts to traditional roofing members.

Garage sale bonus's

Mine doesnt have 'em either.

Probably a common used measurement by the original owner ... as already mentioned,
... or maybe it fitted on a coupla pins in a portable toolbox ??

Whats the measurement between the centres ??

.

Are they threaded?

Yes, those two ideas may offer a clue, particularly if you measure the distance between the hole centres and the diameter of the holes. For example, if they are 90-91mm apart (internal to internal edge of hole) then it would possibly suggest that it was repetitively used to sit over a 90mm wide piece of timber.

If they are threaded then my estimate would be that a couple of pins were screwed into place to sit either side of (say) a roofing member as Stewie suggests, for repetitive use.

If not threaded then they may have just received pins from a jig of some sort in a workshop situation.

There are no holes in the Silex #78 which I inherited from my Father-in-law so it is obviously peculiar to yours and the suggestions made by others are possible.

I would say that the holes if threaded, were used to screw a plate on, so that angles could be marked on something that had a large radius.

I wondered that, but you can see that there is extensive wear over the area between the two holes, so if something like a plate was screwed to to it there area should be a clear patch where is once was.

Of course the gauge could have had several different lives, so the holes could be totally unrelated to the wear.

Sorry I didn't get back earlier.
The holes are 62mm centres and are 6g self-tapper treads, evident by the metal around the holes being pulled out above the surface. I'll just level them off.
Yes, it's a great tool for the shed. It will get a lot of use. The locking key works really well and easy to operate.
I'm guessing it might have been fitted permanently to a machine of some sort.
It was a good pick up. From memory I think I payed $2 for it.
