2071-2085 (15) 9.50 5.65

My main problem is with the 20pf and the 50pf.  If I do the engraved test with aluminum foil, they are all engraved but the Size does not match up.  I know Scott rounds off and michaelcayley tried to help me in the shoutbox but the sizes he gave me aren't working either.

Any help would be greatly appreciated.

I probably don't understand the problem, but I see them as

1400 series = big
1600 series = coil small
2000 series = non-coil small

[JanetC]

Butterfly The design sizes on my stamps are not matching up to the Scott Catalog sizes. That's the problem.

[Butterfly]

Now I'm getting confused. Scott says coil but doesn't specify horizontal or vertical. Neither does Michel. My DDR stamps are all perfed all the way around.
BTW: Michel says 21.5 x 17.5 for the 1600 and 2000 series.
I presume you are measuring design only?

[JanetC]

Foreign coils are not like US coils,,they can be perfed on all 4 sides.

Yes,, measuring design only. let me try the Michel sizes and see if that fits.

[Butterfly]

I have two of the small 20s. One is slightly larger than the other, both appear engraved. Variable paper shrinkage responsible?

[JanetC]

21.5 is better than the 22 that Scott says,,that works a lot better

Just so you are aware.in my experience Scott almost always rounds there measurements up.. perfs, design size etc....
