If that's the case it is a shame it wasn't passed on by a 1901 member, in which case it would not have been a problem. The hypocrisy of it all stinks.
1901 members are not allowed to transfer away game tickets, only their home ST. Exactly the same as for other ST holders who have purchased a seat licence.
It is the purchase of the seat licence that grants the holder the right to transfer their home tix. 1901 seats come with the licence as part of the price; other ST holders have it as an optional extra.
