You might try calling AM YISRAEL. I found a hit for "Fred Steinlauf" on one of thier PDF newsletters. I think he is dead though, (Yahrzeits?), so you would have to ask about his kids. I guess you might have to ask some questions to see if he is the right Fred.

I mapped the shop at 3851 Ogden and the Synagoge and they are only 23 miles apart.
