Company logo - large press

[BurningTantalum]

I have been tasked with a repair (probably electronic) on a large press. It is VERY heavy and installed tight against a corner so I can't access the rear.
Just out of interest does anyone recognise the company logo on the panel, which contains the 3 phase contactor and a timer pcb for the stroke time?
It may be American or Japanese but I didn't measure any mechanical parts to see if it was metric or imperial.
The pcb looks as if it is a 70s design - laid out using 'tape and dots' with lots of cross-hatching ('thieving') on large traces, laid out unevenly by eye.
Also does anyone recognise the footprint for the dpdt 24V relay, which has been replaced by a standard type on flying leads? It is definitely metric.

Are there any clues on the PCB?

Is there a sticker on an EPROM or something similar?

Can you identify the ICs? Are they American or Japanese? Date codes?

Thanks for the reply. The pcb is really simple, with a 556 dual timer, an opto isolator, relay, triac and supporting components. I have repaired the pcb today and will reinstall tomorrow, but I was just interested to know who made the press and where.
It looks as if the opto and the 556 were made in 1981 - 556 is National, code M8147 and the opto is Motorola, code 8108.
The triac was dead, a 22uF electrolytic was corroded to dust under the shrink sleeve, and two 220uF res caps had legs rotted off, and a to92 transistor was crushed under the loose relay. The owners claim it was working last week !
The whole inside of the cavity was covered in a black 'woolly' sooty deposit that tested as conductive (1meg with about 3mm between the probes.) The pcb was buried in it, and I thought on site that it maybe contained cast iron filings but it is not magnetic. The owners use the press to die cut sheets of vacuum moulded plastic trays, and say that they bought it from a leather goods manufacturer -  who knows where it has been since the 80s !
It looks very similar to the attached pic.

Here's your logo: http://www.logobook.com/logo/united-shoe-machinery-corporation/

Thanks Nusa, I didn't even try searching for the logo on the net because I couldn't see that it was feasible. A useful site that I have bookmarked.
The company certainly has an interesting history - and ball turrets for Boeing B17s too !

That's just the first site I found it at. I actually found that site by snipping the logo and using image search tools. And once I had a name, the rest was easy.
