Park made these all thru the 1970s first they were chrome steel with plastic coating then they had an alloy version. I have an alloy version I use with a Lafume front bag (in fact I used this for L'EROICA one year) They also had a nice clip on rear bag support which was available in 2 sizes tall and short which you could use different bag sizes and frame sizes. I recall selling many of these wholesale when I was at Wilson in the 70s but dont see many these days. I will have to post a photo to wooljersey. Will use this tomorrow as we are expecting rain and I am signed up for the full Wine Country Century . I will need space to stash warm clothes and something rain proof
