[Hallicrafters] Anyone have an S-40B they're parting-out?

[SX-25]

Looking to buy for an S-40B restoration:

     2nd I.F. coil (T2) - This is the one farthest back on the chassis and is 0.775 x 0.775 x 1.8-inches in size. Hallicrafters part number is 50C243 and the same coil is used in both the 2nd I.F. and 1st I.F positions.
Apparently an I.F. coil from earlier versions of the S-40B will not work in their fit on the chassis because they are larger.
I've tried similar coils from Hammarlunds and I seem to be experiencing some lousy roll-off and tracking issues.

     Thanks!
