Curt Cheeseman send me photos with three versions he has of the Taylor made wrist compass: with markings, without markings and with an aluminum base. It’s the first photo I’ve seen with all three types together and it makes for an interesting comparison.
The shape of the base is identical for all three. What stands out on the bezel is that the Taylor logo isn’t always at the same compass position.
We still don’t know in which order these variations were manufactured, but it stands to reason the aluminum base was the earliest version. It’s what I think because aluminum was rationed during the war and there are very few compasses still around with an aluminum base. More information on this, should anyone have it, is always welcome!
