Reynolds 531C versus Singer 431G

Vintage Reynolds 531C bicycle frame tubing & Classic Singer 431G Sewing machines?

Why? What is the comparison? 
Bit of a mad one maybe, but I was thinking 'Crossover'.

In the early 1960s if you were a cyclist in UK a top option would be a Reynolds 531 frame.

In the early 1960s if you were a 'sewist' in UK a top option would be Singers 400 series sewing machines. Slant-O-Matics. 

Both being at the top of their 'curve' in the 1960s. 

That's the connection. Experience with both tells me there is a considerable & satisfying crossover between the two. Knowledge of one helps the other, I say.

That is my 'Thought for the Day,' but more to follow. Possibly.

Classic Singer 431?

The Singer 431G is the last of the best machines Singer made. IMHO. The Japanese finished Singer in the late 1960s, (As they did with motorcycles/cars/electronics; ) by producing better items at less cost.



Classic 531 frame?

This is a late 1940s Bates Vegrandis, with its distinctive forks. Slightly exotic, amazing even, bulbous 531 tubing, but it was a top 531 choice in its day. 

Come the 1960s 531 was looking old, but cool technology. As with Singer? Alloys came along, then carbon fibre.

I rest my case here.
