Berry Shock Absorber Seat Post

[TR6SC]

I just found this. Looks like it's in great shape. No rust, just loss of nickel.

The balls ride in the grooves. Two cups and a cut-out washer center the balls. The spring has a tension nut for adjustment.

I think it's a double R. BERRY, or on second though, I think it's BERKY.

Ran a Google search of Berkey bicycle Grand Rapids and found this ad from 1901.
The ad was from McClure magazine and there was also the same ad from a 1901 Cosmopolitan. Getty images also has a copy of the ad.

What diameter is the post? Looks pretty big for most down tubes.

Seen these on a couple TOC bikes. Bet they made for a comfy ride.

I thought the same, but it is 7/8". I'm going to use it on my 1897 Sterling.
