If I remember correctly, till about 1970,the Tigercat had the year of manufacturer in the first digit of the serial number, above the bow weight and length. Most of the 62" Tigercats were made in the 60s,switching to a 58" bow length in the early to mid 70s.
Should put your bow as a 1966, the 1953 being the year of patent, a fiberglass lamination process patent, again, IIRC..

Good bows, I like the grip on them. Rug rest or a feather rest, new side plate, I,d put a new flemish twist string on it if it were me,tips are NOT fast flight compatible.
If your draw length is right around 28-29", 500 or 400 spine gold tips depending on the weight up front should have you in the ballpark..
