I was looking at Swiss UPU 1900. This site tell that the Type I are 22mm height and Type II and III are 23mm height, (including perforation)? But the stamps are about 41mm height! The catalogue Michel swiss spezial 2017/2018 say "Markengröße incl. Zannung" witch I think must be stamp size included teeth? And then I think we are talking about the with of the stamps? But then again, None of my stamps are 22 or 23mm, they are at least 24mm!? So, how to tell type I and II from on another? You could use the perforation as the type I has line (horizintal between 11½ and 12, vertical between 11½ and 11¾) and type II (and III) has comb 11¾. Here are my 5C stamps. The last row is type III, identified by the dash line between 1875 and 1900 straight. But the rest I can't identify correct. The perf is as follow: No1: 11½ x 11½ No2: 11½ x 11½ No3: 11¾ x 11¾ No4: 11½ x 11½ No5: 11½ x 11½ No6: 11¾ x 11¾ And the type II No7: 11¾ x 11¾ No8: 11¾ x 11¾ No9: 11¾ x 11¾ 
I don't have the knowledge to see the different on line and combinated perf. But I see that stamp 7 to 9 has even corners, and so has stamp No6. They all has perf 11¾ x 11¾. Then its stamp No3 who also have 11¾ x 11¾perf. But the corners are hard to identify. Can I assume stamp no 1, 2, 4 and 5 are type I. Stamp no6 are type II. And maybe stamp no3 is type II based on perforation? Stamp no7-9 are type III based on line between 1975-1900 and the 5 and perforation. What do you think? |

Hello tobben I found this site :- www.stamp-collecting-world.com/swissstamps_1900c.htmlWhich says:- Plate I All of the impressions on the plate are 2.2 mm apart, and all the stamps from this plate were line perforated approximately 11 3/4 x 11 1/2. The line perforation device consists of a single row of teeth. The perforation process is applied separately to each horizontal and vertical row of the sheet. With sheets perforated in this manner, the crossing of the horizontal and vertical rows of perforations is irregular. This results in the corners of each stamp being irregular looking and in the horizontal and vertical perforation gauges being slightly different. Plate II All of the impressions on the plate are 2.8 mm apart, and all the stamps from this plate are harrow perforated 11 3/4. In this perforation method, the pins in the perforating machine are arranged in little rectangles or boxes (thus the German term "Kastenzahnung" or "boxed perforation") that are the size of each of the stamps. With the downward stroke of the apparatus, all the stamps in the sheet are perforated in a single process. This method results in the corners of each of the stamps being the same and the individual stamps being the same size (perforation gauge). I hope this helps Regards Gavin |

But then again, None of my stamps are 22 or 23mm, they are at least 24mm!? The size 2.3 & 2.8mm designates the spacing between stamps which will not mean much with single stamps.
The Plate I & II are mainly distinguished by the perfs. Easy with 2 or a block but the corners are the key The comb perf has nice even indented 4 corners
For the type I & II 5c the perfs are the basic guide
For the 10c also but there is a slight difference in the value   Type I & II This is not completely foolproof but generally aside from the perfs, the Type II comb has a lot of broken line detail around the value
The 25c is easier  Type I - 3 lines above the value
Type II - 2 lines above the value
 Type III re-engraved plate 3 lines above the value
AND the key to all 3 values - the numerals of the Type III haves lines in them, the Type I & II are flat
The Type III 10c & 25c are not common
I am not sure that the hyphen difference is valid as a characteristic

Thanks a lot Gavin. This comfirm what I was assuming. Learnt a lot today.
Strange how bad cataloges explain this, even special catalogs. With bad illustrations and complicated explanations. If cataloge produsers don't take this serious, they will not survive I think.

Another good reason to collect pairs, strips and blocks.  Although the perforation gap increasing does mean the stamps perf to perf are different in size by 0.6mm. The way to tell is by adding the width of the printing to the gap minus the width of the pin which would give you the width from inner edge of perf to inner edge of perf: 21+2.2-1 = 22.2mm or 21+2.8-1 = 22.8mm. |
