Question about Parlophone and Canadian stampers and Rubber Soul (Loud Cut) | Fab Forum | The Beatles Bible

(I hope I’m writing on the right thread.)

I have a few questions regarding some Beatles vinyls I’ve purchased at a vinyl fair some days ago. While looking at the stampers, mothers and lacquers (I’m not the type of collector who would only buy records with 1/G 1/G stuff only but I like delving into the vinyls’ pressing history) I came across some writings that I couldn’t explain. The first one regards the 3 o’clock position on the B side “This Boy ” which has a letter R and a letter A with a 0 as its’ subscript. The second one regards  the 9 o’clock position on the A side “Can’t Buy Me Love ” where the mother is 0. Lastly, what does it mean if there are 3 letters on the 3 o’clock (stamper) position? Does R GM mean stamper 214?

My last issue regarding the stampers, mothers and lacquers is about a 1982 pressing of the Canadian edition of The Beatles Reel Music (the ordinary one, not numbered). It has some letters etched by hand that I couldn’t find anywhere online:

TL(?)C.T. on 3 o’clock position on side 1 (I took the photos from a different angle but the position is the one stated, my camera isn’t the best one)

k.e.y. on 4 o’clock position on side 1

a circular sign on 9 o’clock position on side 1

and a “ma” or “mu” writing on 12 o’clock position on side 2 of which I couldn’t take a picture because it was impossible.

If the pictures can’t be seen well I’ll try to take a close-up picture but it might be hard.

My second question regards the Rubber Soul Beatles album. I would like to purchase the Loud Cut first pressing if I find it at the next vinyl fair but I’ve read some bad reviews regarding the Loud Cut. So, would it be better to get the following pressing or is it just simply a question of taste?

Any help would be much appreciated!
