Sturmey FW springs

I have a couple of near-mint FW hubs which (presumably from having been parked in a low gear for decades) have short compensating springs, under 1 1/2" long excluding the collar. This means second gear slips.

Can the springs be stretched to get them back into spec (at least 1 9/16")? The service manual says "fit new spring set" but they have been obsolete for 52 years!

I could send the hubs to a specialist but I don't need a rebuilding service, just the springs!

They might be donkeys years old but BITD we had drawer fulls of SA spares. Are they for sale somewhere, I guess there must be some kicking about.

None on the Bay of Thieves, and none in Sold Items either, which suggests they're uncommon.

The spring rate is quite critical, I think - selection of 2nd gear relies on one spring overcoming another. For a small spring, it is quite stiff.
