Hot Rods Can anyone I.D. this Amp gauge

Just bought this Amp gauge. I have seen this same font before, but for the life of me I can't think where. Can anyone help please.
Cheers,
Stewart.

 

It's aftermarket, you know....and not having a name on the front, means it's probably an off brand.

 

I've got some. Looks either AC or Rochester

 

I have seen those before with the stylized "O". Kinda looks like the Plomb tool logo...well, to me at any rate. Don't know the brand. Sorry for the lack of info, but at least you got a bump out of my post.

 

Stewart, are there any numbers on it? If its an ac gauge I may be able to find the application by part number in one of my united books

 

To me generic, 50s-60s maybe?

I have an oil pressure gauge with the same Os. It says Rochester Mfg Co.
PM me if you want it, just pay postage.

Looks like Bob got it. Rochester Mfg. Co.
Thank you. Now if I could only remember where I have seen them before. The distinct Zero and letter E made me think it was 40s 50s.
Cheers,
Stewart.
