Our church has a Steinway in the sanctuary, and I’m trying to figure out what it is. The metal plate holding the strings appears to have been painted because the place where the model letter usually appears is blank. I did find this at the end opposite the keys - does it reveal anything about the model and/or vintage?

That was quick, thanks! Does that make it an A-3?

Yes. Also the A-III will have a curved bass bridge

Can you tell us how these plate markings indicate 1917?

Steinway A (third version), or A III, is the so-called "Small Parlor Grand" -- first made in 1913 (No 163422), and last made in 1945 (No 318269). The length is 6' 4 1/2".
As mentioned, the bass bridge is curved. The AIII has 231 strings, with an overstrung 20-note bass section. The plate has 4 cooling holes, each surrounded by 2 raised rings.
The Official Guide to Steinway Pianos (by Roy Kehl & David Kirkland) has additional info.

I believe that the numbers represent the date the plate was cast, with the lower number being the number of the plate in that year's series. Starting in 1910 they switched to a letter code to represent the year, working alphabetically (but skipping the letter "I", I think). The letter "G" thus works out to 1916, but the piano probably wasn't finished until the following year.

I understand working out the date. I’m guessing something in the picture shows the curved bass bridge? If not, what in the picture tells us it is an “A”?

Both A's have 10 wound strings above the bass/tenor break, visible in the photo. I appreciate the ability to decipher the age from the casting numbers, putting the age range in that of the A3's. If you want a more obvious verification, step back and include the bridge in a photo.

FWIW, we have seen Steinway plate castings that were many years separated from the production year. The best solution is to keep looking for the serial number which will be located on the key slip, key frame, legs, lyre, or several other case parts.
