alternate gothic

Certainly looks like Alternate Gothic.

Would you know what weight?

The caps look taller than on versions I've seen.

i think angel71 has got it right, although mr larabie has sailed very close to the wind on the plagiarism front with steelfish!

Never seen Steelfish.

Need to look it up now that you say there's something fishy (sorry, couldn't resist that!)
