I had a couple that might work.First one is the UTG SW080B. It's an 80mm wheel with an ID of 1.119" for the knob. It has a rubber insert that will grip the knob when you install it and tighten the set screws.$14.97 plus shipping.The other is the Center Point CPSWF. It's a 100mm wheel that also has the rubber insert and an ID of 1.117". $9.99 plus shipping.I think either will work on your scope with the knob 1-1/16" diameter.http://centerpoint.crosman.com/accessories/CPSWF
You can make very professional looking custom tapes by using any CAD program to draw the tape......then print it out to scale on an Avery 5126 adhesive backed shipping label. Once printed, put a piece of packing tape over the printed tape. This will protect the printout from moisture or smudging. After that, just cut the thing into a strip. I used a paper cutter that my wife has for scrapbooking......but you can easily use a straight edge and an exacto.Peel and stick after that. They are very durable.There are tons of free CAD programs available that will easily do the job. I suppose Photoshop would work fine, too. Anything that will allow you to design and print in 1:1 scale.Just put masking tape on the wheel first......then use a sharp pencil to mark your exact ranges on the masking tape. Make sure to put a mark on the wheel that shows where the tape begins, too. Remove the masking tape and stick it to a flat surface, then use a caliper or something to transfer the measurements to your CAD drawing of the tape.Once you have your ranges correct......you can also make tapes with turret settings, holdover amounts or mildot corrections instead of yardage. I posted a pic of my master that has yardage, turret, and holdover in inches, and my gun which only uses turret settings.It really is easy.....and making a new one is a few minutes of work.Mike
