Collecting : My collection 04 f

Some examples of how the la Gasse-meter works :

Some examples of the stamps I tested:

1. Make sure the stamp is exactly in the middle of the central square:

2. Make sure the overlay is exactly in the position of the cancel

3. Result : 150
This is a very good cancel indeed; 150% of the value

the box indicates : 150

Another example:

1. Placing the stamp:

2. Placing the overlay:
Here, the cancel is bigger then the overlay indicator,
so you'll have to find the center of the cancel.

3. Reading the scale:

scale : 150

The scale indicates a 150%, but the cancel isn't clear enough to reach that percentage.
Altough it's very well centred, due to the lightness of the cancel, the value is lower.
So certainly a 'downgrade' to me.

Last example:

1. Here I placed a larger stamp on the A-sheet.
The hight is larger than the width, so we have to adjust the hight when placing the stamp.
If the stamp is wider than its hight, we have to adjust the width of course.

2. Placing the overlay:

adjusting the stamp to the compass, and the 2nd compass to the stamp

3. The result:

aww, only 40

With small 'classic' stamps, the value would be 40%, but as this stamp is larger, it's in fact a very good cancel too, as we can see the full name of the city (here : Bucureci - Bucarest) and the full date of cancelation : here Jan. 28, 1914.
Definitively an 'upgrade' to me.

Lesson to be learned.
This is a handy tool but it's not a Bible.

Have fun measuring !
