That's right, you get to identify my perfins while I look on in awe- well, something like that. Now I apologize if I put this in them in the wrong category, but I don't know much about this. They are listed below, as my scanner is currently not working.
PAC on a 1d stamp- design a81 by Scott. I'd say it's it's #152, but I know nothing about identifying these stamps. The cancel is from 1921.

Ld on the 5d #118, also one on the 2d #113. one has a London cancel. (The smiley is supposed to be W T F) If they still make items (assuming they were into manufacturing) I think I might have some of the things they made

OSIR on 1d #293
H on 1/2d s #127, just a simple "H". Cancel from 1904
UCL on 1d #281, pair
MOSS on 2 1/2d #114. London 1896 cancel. What does MOSS mean?
B C on 2d #295. kind of interesting because it's my initials. It has something to do with
forestry (I soaked it off an envelope without checking the return address!

)
S&L on 2 1/2d #82. Large lettering
S&L on 1/2d #112. It has much smaller lettering in the per fin above
L&S on 1 1/2d type a84 by Scott.
S&S on 1d #89. Large lettering
B T. H on 1/2d #111, as well as on #126
S B C on multiple different wildings ( I think that's the right name)
HM on 2 1/2d #296.
J & Co. On 1 1/2 #112.
JT & Co on 1 1/2d #112. it has this strange diamond cancel with FS in the center of it.
I think that's it for now. I hope I didn't waste everybodys time. Is there a place or book I could get the info to figure it out myself?
