Moroso Crank Pulley

[Riverbud]

Need some help identifying the crank pulley on a big block Chevy. Can make out Moroso and looks the last 3 digits are 425, but the first digit is difficult. Did some image searching with no joy. I'd like to keep the car Day 2 and want to see if this is period correct for 1969.

Thanks, thought it might be a 6 but that didn't bring up anything. I did see a reference to it being for a BBC but the link was dead. Not much information out there on this.

I have one just like it I bought back in the early seventy's, I think it's in the original box. I had it on a LS6 motor to run something. but can't remember what.
