Can You Help Me Date This Men's Suit?

[Boutique369]

Hi, I just listed this men's vintage suit in my shop that I think is probably 1960's but a few people I asked thought it was 1930's based on the metal IDEAL zipper on the pants & the style of the jacket. But the pants, in my somewhat educated but by no means an expert opinion, think pants looks 1960's. I just wanted to be sure. There are no tags of any kind to give me any cues. Grey pinstripe with 4 button closure jacket that looks a bit western but it's subtle. I appreciate any advice. Thank you. CLICK HERE TO SEE MENS SUIT

Most everyday suits and casual trousers in the 1930's featured cuffs, that's turned up hems, to add weight and help the wide-leg drape straight. The photo shows no such feature.
Check the flies, Buttons remained the traditional and most common choice in the 1930's, especially for higher-end tailoring,
Two top pockets with external flaps on jackets, suits, and blazers were most popular during the 1950's. The jacket in the photo has such a feature. It could have been a bespoke request but chances are that suit is circa 1950's.
