Odd and weirds scripts. Are the following spendable?

[DeathAndTaxes]

1 of 1 MULTISIG
Is a 1 of 1 "multisig" valid?
OP_1 <PubKey> OP_1 OP_CHECK_MULTISIG

Example hasn't been spent but w/ a 1 satoshi output I don't think it will be.  Is output 20 otherwise valid?

P2SH "Spend" without a signature?

Code:

getrawtransaction 6a26d2ecb67f27d1fa5524763b49029d7106e91e3cc05743073461a719776192 1

Ok Input references unspent previous output 9c08a4d78931342b37fd5f72900fb9983087e6f46c4a097d8a1f52c74e28eaf6:0 (txid:index) which is
"scriptPubKey": "OP_HASH160 19a7d869032368fd1f1e26e5e73a4ad0e474960e OP_EQUAL"

"Pay to the Script which hashes to 19a7d869032368fd1f1e26e5e73a4ad0e474960e".  Ok good so far.

The input ScriptSig is 5121029b6d2c97b8b7c718c325d7be3ac30f7c9d67651bce0c929f55ee77ce58efcf8451ae

The HASH-160(5121029b6d2c97b8b7c718c325d7be3ac30f7c9d67651bce0c929f55ee77ce58efcf8451ae) = 19a7d869032368fd1f1e26e5e73a4ad0e474960e
So redeemScript is correct (hashes to ScriptHash).  Looks good so far.

The bolded 0x21 means push the next 33 bytes (the compressed PubKey).  Right?

So decoded we have:
OP_1 0x029b6d2c97b8b7c718c325d7be3ac30f7c9d67651bce0c929f55ee77ce58efcf84 OP_1 OP_CHECK_MULTISIG

Ok another 1 of 1 multisig except a P2SH version this time.  We need the tx signed by 1 signatures from the set of 1 PubKey(s) {029b6d2c97b8b7c718c325d7be3ac30f7c9d67651bce0c929f55ee77ce58efcf84}.  Right?

Except there is no signature.

Here is the Raw Transaction:

0100000001f6ea284ec7521f8a7d094a6cf4e6873098b90f90725ffd372b343189d7a4089c0100000026255121029b6d2c97b8b7c718c325d7be3ac30f7c9d67651bce0c929f55ee77ce58efcf8451aeffffffff0130570500000000001976a9145a3acbc7bbcc97c5ff16f5909c9d7d3fadb293a888ac00000000

The redeemScript is bolded.  The blue is the TxOutHash, the green the TxOutIndex, and the red is the Sequence (end of input).  No signature for the 1 of 1 multisig.

Tx was included in a block so what am I missing?

Heck, a 0 of m CHECKMULTISIG is valid...

Your P2SH transaction is from prior the P2SH turn-on date, which is why it was allowed into the blockchain at that time.

is some data (ASCII-art?) stored in the blockchain
and, yes, all these outputs are unspendable. because these pushes are not public-keys
