bold with stroke or black

Maybe Swiss 721

Yes Heavy.

Mmm... still, can see some very minor differences though

PS: glad someone revise my suggestions too

Really?

Very subtle differences I must admit, but you can try it too maybe it's just me.
Anyway, it could be a "free version" of Swiss, if you know what I mean Maybe we even have it here @DF

I know better than to argue with your keen eye!

I actually used PS for that

It looks like Arial Bold to me.
