Anybody like to decode this model number for age? Old Westinghouse.

I bought a house with an old furnace. Insurance company wants it replaced if it’s 30+ years. House was done in 1978, and I figured it was original. After looking at the model number, I was thinking maybe it’s an '82?. I googled a little bit to no avail, so I thought I might make a post here.

Also looks to be a 66,000 BTU output? Should I use this number to size the replacement when it’s time?

Thank you for any help guys/gals.

I believe it’s August 1983. The V tells me August (skip O & Q), and the first number is for a year, so 1973, 1983, 1993, 2003. But since Westinghouse got out of the business in the early 1980s, and the house was built in 1978, I’m going to go with 1983.
