I recently moved into a 32 year old building and find that the windows are very hard to operate. It looks like the serries 370 with 15-002 shoe and 19-004 top match the print enclosed. If this looks the correct match please send pricing. There are over 100 condo units which have this difficulty.
The window weighs 18 pounds, and there is a marking on frame of "32C".

Hello! I agree, the Series 370 looks like a close match. If the sash is 18 pounds, I recommend the 2230 stamp. All pricing can be found on the S370-23 store page.
