Measure the exact outside diameter and be sure of the tooth count. I have a bunch of 14DP 14.5PA gears and a few 52 toothers if that is what you really need. You would only have to bore it out to 1.250 as all the gears I have are in the 7/8" bore range. A 52 tooth gear would be $20 plus shipping. Would fit in a small flat rate USPS box. Shipping around $5.00. Let me know via private message here on PM.
