Ho ricevuto questa richiesta:
Dear Sir,
I am a thematic philatelist from Pakistan and have been visiting your informative webpage for several months. The information and images there helped me a lot by solving many of my problems and I owe you for this help.
I collect mountain k2 on thematic basis. Italy has issued several special postmarks on this topic. Some of them are still not in my collection. Though I have searched for them a lot on the internet but all in vain. Therefore, I decided to contact you hoping that you can help me out. Can you please guide me where to get them from? or any other information/tip?
I am hereby providing you the details of the required material for your kind perusal.
Out of 4 required postmarks, 2 of them are also on your webpage.

(1) Bulletin : 05/05/2004
Number: 474
Date : 02/05/2004
Location: Trento

(2) Bulletin : 27/05/2004
Number: 671
Date : 22/05/2004
Location: Genova
The other 2 postmarks are quite old and they are:
(1) Issue date: 10/10/1954
Location : Catania-Etna
(2) Issue date: 28/7/1984
Location : Bormio
Can you please help me out with these things or a tip?
Thank you for patience and time.
Regards Waseem waseem157@hotmail.com

Lo consigliato di conttattare Sergio Berti, ecco la risposta:
Dear Administration,

Just like you advised, we tried to talk to Mr. SERGIO BERTI but did not get any answer. Perhaps he is busy now a days or he can not help us.
Is there any other way to get those postmarks that you may know?
Regards Waseem
C'è qualcuno che può aiutarlo?
Grazie
