Given that LU has effectively scrapped magnetics for seasons I thought
the position was that LU issued on to Oyster cards for the Travelcard

In the reverse direction (i.e. purchase at Hertford East then a magnetic
season would be sold).

Well I've certainly seen paper "out-boundary" issues from LU Ticket
Offices "post Oyster", though those were mostly point to point
(generally South Ruislip to Gerrards Cross weeklies).

Always a good way of confusing passengers, by issuing them a Travelcard
instead of a point to point on certain flows, 'cos it was cheaper...And
still is, despite my having informed the appropriate people!

For example: Gerrards Cross to Wembley Stadium point to point Annual is
£1476. Gerrards Cross to Zone R456 Annual Travelcard is £1428.
