lambda gtWES

[MIcha Ron]

Who can give some advice on lambda gtWES?
I need a priming site for PCR from the left and right arms outside the 
ecoRI site of gtWES. Searching for the sequence in the standard 
places(genbank or BRL, whom markets the vector, came up with nothing). Its 
a very old vector and not many researchers around today 
have experience with it.  The restriction maps for gtWES and wildtype 
lambda are exactly the same according to Maniatis (1982). Can I assume 
homology for the sequences flanking the ecoRI site and base my primers on 
the sequence of wildtype lambda?
