There was two of them. Bought for the longer Dentressangle trailers. Horrible things to spend a week away in.
All the c-series ERFs came with the E320 and 9 speed, with double drive.
All the B-series had the E290 except for the one I started on as a 24 year old newbie that had a 240 Gardener
The last new Foden came home with the E400, now that did fly and with the 3 position Jake also stopped!
