Mcculloch 1-53 4.9 or 5.3 CID?

[MotoBoyMatt]

I have an orginal Mcculloch owners manual for a 1-53 and it states the displacement of this saw at 5.3 CI (87 cc) but Mike Acres site http://www.acresinternet.com/cscc.n...3647dbba2713bb3488256b00006b8fac?OpenDocument shows it at 4.9 CI (80 cc).

Any thoughts

According to my microfiche ,the 1-52 and 1-53 are 5.3 cu in or 87cc.1-52 was made from 1961-62 and 1-53 from '62 to '63.
