Wore out three sets of tires already!
Your bike is the best preserved CCM I've seen of that age - very nice find! You have holes in the rear fender to lace a skirt guard. I'll post a picture from the 1918 and 1924 catalogues so you can see how it was done. You can see that in the 20s CCM introduced the dropside fenders and removed the bottom half of the chainguard. Yours still has vintage tires, please don't throw them out! You will have a tough time finding ones that will fit well on the wood rims, and they won't look right. If the rubber is still soft just replace the inner tubes. If the rubber is rock hard, consider leaving the tires alone and keeping the bike for display and not riding it. Yours has Gibson aluminum pedals, a top of the line upgrade. I will also attach a photo of my 1927 girls CCM Cleveland, which is more typical of the condition you find these bikes - a bad repaint on the everything including the rims. Children's bikes had 26" rims and adults the 28" rims. The girl's bike did not come with chain guards for some reason, but had the holes in the fender for lacing and retained the older style fenders.
