I haven't been able to find any pics of a coin-op GE with the front panel removed.
Sad truth of it is, it's been 25+ years since these were made, they weren't particularly popular due to service issues and the water wasting that would cost owners $$. I'm sure most people were happy to see them go to the crusher.
With the front panel removed it looked the same as the BACK side of a standard FF washer with the back panel removed but you didn't see the inlet hoses as those were on the other side and the drain hose was piped to the other side.
This relative I helped out with in the early 80s had a service contract for a large apartment complex and they had all GE appliances. Wall AC units under the windows, dishwashers, top mount refrigs, stoves, and coin-op laundries on every floor of each building.
A couple of washers needed to be replaced once and instead of buying new coin-op machines the owner just bought new basic BOL GE washers that we popped the top off and put the top of the worn out washer on to the new base.
It was obvious for those with a discerning eye because the new washer was white but the old coin op was harvest gold. But it was a good way to save money.
