Hi there- thanks for posting! 

I was able to narrow what you have down to two options. You either have our Series 380 or our Series 385 channel balance. The difference lies in the depth of the shoe. The series 385 balance has a 15-004 shoe, which is 1-3/32” deep while the Series 380 balance has a 15-005 shoe, which is 1” deep. It looks to me like you have the Series 385, but I can't be sure as I can't tell the exact dimensions from these photos. 

Please reference the below photo to see exactly how to measure the depth of your shoe to determine which series you have.

Once you determine the correct series of your balance, you will select the 27" length with a 2640 stamp "option". For the other balance you will select the 23" length and a 2240 stamp "option".
