Hello Summit,
welcome to this forum and greetings to York, the city where Mr Norrell performed his tricks in 1806 (though I'd really be surprised to read about him in a contemporary letter). Pre-philately can be challenging, but there's room enough for everyone and many pieces are available at modest prices. Just show us what you have—I'm sure several members will be interested and can provide you with reliable facts or at least an educated guess (and very often in English, to boot!).
Best wishes
Dietmar
Dear Dietmar,
Thanks for the encouragement! And for suggesting about Mr Norell: wasn’t aware but would find out for sure.
I’ll get going and come back soon with my samples - sounds exciting, learning times ahead.
Regards
