if you have no access to this server a restore of the msdb on your server as a user database would give you the information you need, no other information is needed.

You could ask them to run this query and return the results to you

SELECT [rs].[destination_database_name],

[rs].[restore_date],

[bs].[backup_start_date],

[bs].[backup_finish_date],

[bs].[database_name] as [source_database_name],

[bmf].[physical_device_name] as [backup_file_used_for_restore]

FROM msdb..restorehistory rs

INNER JOIN msdb..backupset bs

ON [rs].[backup_set_id] = [bs].[backup_set_id]

INNER JOIN msdb..backupmediafamily bmf

ON [bs].[media_set_id] = [bmf].[media_set_id]

where [rs].[destination_database_name] = 'SGCTI'

ORDER BY [rs].[restore_date] DESC

If you restored the msdb you would have to amend the database name you queried in the code above
