Help identifying a deck

[gtrman_66]

Hi all.

I was wondering if any of the good folks here in the analog forum can help m identify this reel to reel unit so I could possibly find some info and maybe a manual for it. It says it's a Sears model 524, but gawd knows what it actually is considering all the different manufacturers that made stuff for sears over the years. Anyway, it's a 1/4" 1/2 track with 1 7/8, 3 3/4 and 7 1/2 ips speeds.

It belongs to my boss at work and I'm trying to help him get it going again.

Thanks
