hello...

Does anyone knows about this bowling ball?
I am a bowler from Taiwan, we have this ball for a long time
The ball ID is 53D5337, we guessed the ball was made in year 1995 or 1985 but we dont know who is the manufacture.

I got the opinion that it may be a private label ball, does anyone here may recognize this ball and tell me who the manufacture is?
very much appreciated!!

Below are the links to the pictures of the bolwing ball..
