i have a p2sh address that is created using an uncompressed public key (from my ledger nano) and a compressed public key (bitcoincore wallet). It requires both signatures to send the funds. When i use my nano ledger to sign i get output:

3045022100b0c80ad5f5db6b790b75156186322b1fd6f9d1da61ff04e47f5a64ca8cdfaf6f02207bce077a537e215d9dd5ccaae72e8af1c4750e67722910c2af1d1f3b6e9357f2

I am using the ledgerjs library to get this and using the signP2SHTransaction function. Normally i just input my private key into bitcoin core's signrawtransaction function but I am pretty sure this is the scriptSig. I just don't know of any libraries that allow me to use this to sign the rawtx. (I looked at python-bitcoinlib but i saw no way to input rawtx information into a readable format.)

Any suggestions on a tool i can use to take this to sign the raw tx hex to the send on the wire?
